摘要： PURPOSE:To enable the control of the entire range of flow rate of a fan in a method, by fully opening a suction damper to control the flow rate when the rotational frequency of the fan is not lower than a lower limit, and by adjusting the degree of opening of the damper when the flow rate is not higher than a value corresponding to the lower limit to the rotational frequency. CONSTITUTION:The suction damper 12 of a fan 1 is controlled by an opening degree command signal S3 from an operation unit 13. When the rotational frequency of the fan 1 is not lower than a lower limit, the suction damper 12 is fully opened to control the flow rate of the fan. When a flow rate not higher than the flow rate corresponding to the lower limit to the rotational frequency is to be obtained, the rotational frequency is held at the lower limit and the degree of opening of the damper 12 is adjusted to control the flow rate. The entire range of discharge flow rate of the fan 1 can thus be controlled.

摘要： PURPOSE:To increase heating capacity under high load and thermal efficiency under low load by increasing stepwise the pattern for setting furnace temp. for each of the zones in the strip line direction when the strip load is off the prescribed value. CONSTITUTION:The heating furnaces of a continuous annealing installation are respectively divided to four zones. Fuel flow rate controllers 11 are controlled by furnace temp. controllers 8 to control combustion rates so that the furnace temps. detected by thermocouples 9 for each of the zones attain set values 10. A pattern for setting the furnace temp. is applied to increase stepwise the temp. of each zone in the strip line direction when the load of the strip heated in the heating furnace is the high load of a prescribed value or above and when said load is the low load of a prescribed value or blow. The reqiured fuel flow rate is thus controlled to the max. flow rate or below in the case of the high load and the target value of the pressure of the waste gas is controlled to the lower limit value or above in the case of the low load, by which the prescribed control of an air-fuel ratio is accomplished and the decrease in thermal efficiency is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a fuel cell control system using a fuel cell and a secondary cell, controlling the amount of power stored in the secondary cell to be at or above a reference value at all times, permitting stable assistance by the secondary cell, and controlling a change in the flow of fuel to a reformer to be within the capability of the reformer, with the reformer supplying fuel cell gas to the fuel cell. SOLUTION: The fuel cell control system is provided with a secondary cell stored power control device for detecting the amount of the power stored in the secondary cell to determine the target output value of the fuel cell which sets the amount of the stored power at or above a reference value, and a fuel cell output control device for detecting the output of the fuel cell and controlling the flow of the fuel to the reformer so that the detected value becomes the target output value of the fuel cell. The fuel cell output based on the flow of the fuel controlled by the fuel cell output control device is imparted to the secondary cell via a DC/DC converter to control the amount of the stored power to be at or above the reference value at all times. Also, the fuel cell output control device is provided with a rate limiter for limiting the flow of the fuel to the reformer so that its time rate of change does not exceed the response capability of the reformer, to thereby prevent an extra supply of fuel.

摘要： PURPOSE: To obtain an intake cooling water inlet temperature stable against the external tubulence by obtaining a feed-forward signal for giving a cooling water amount necessary for a LNG flow rate demand from a thermal balance formula and adding a correction amount corresponding to a difference between an aimed value and prent temperature to adjust the cooling water flow rate in the LNG carbureter outlet. CONSTITUTION: In a LNG combustion as turbine combined cycle power station, cooling water, cooled when the LNG supplied to a gas turbine combustor 5 is evaporated in the LNG carbureter 1, flows to an intake cooler 3 installed in a gas turbine intake duct to cool the intake of the gas turbine. Then, an LNG flow rate controlling valve 21 is controlled on the basis of a detecting value of the LNG flow rate detector 20 and LNG flow rate demand 22. Also, a cooling water feed-forward set value is calculated from the detecting value of the LNG carbureter inlet temperature and LNG flow rate set value according to the thermal balance formula and added to a cooling water flow rate correction value to obtain the cooling water flow rate set value and control a cooling water flow rate controlling valve 13.

摘要： PURPOSE:To control the travel of a crane on the basis of an image process by controlling a travel motor, using a deviation angle detected with a gyro as well as an instruction value calculated from a deviation amount calculated immediately before a guide line image disappears. CONSTITUTION:Two cameras 8a and 8b mounted on a trackless crane 1 travelling along a guide line 6 photograph the guide line 6, and a gyro 9 detects a deviation angle 6 and a deviation angular velocity theta s relative to the guide line 6. While a photographed image shows a guide line image, deviation amounts DELTAx1 and DELTAX2 are calculated by processing the image, and instruction values v1 and v2 available therefrom are used to control a travel motor before and after the deviations. On the other hand, while the guide line image is not being shown, a deviation angle theta detected with the gyro and the calculated deviation amount DELTAx0=-(DELTAx1+DELTAx2)/2 immediately before the disappearance of the guide line image are used to calculate a deviation amount. DELTAx during the disappearance of the guide line image via the application of an equation, and a control variable DELTAv' is thereby calculated. Then, the travel motor before and after the deviations is controlled by use of instruction values v'1 and v'2 obtainable from the calculation.

摘要： PURPOSE:To suppress the pressure variation owing to a poor condition of a main pipe pressure control system, by increasing the LNG flow rate of waiting carburetors adequately when the condition is tripped by using a single carburetor in a low load condition, in an LNG base where the number of LNG carburetors is controlled according to the load. CONSTITUTION:The LNG delivered from an LNG tank 1 is gasified by carburetors 3 to 5, and after being collected in a vaporized gas main pipe 6, it is fed to the customers. In this case, according to the output of a detector P to detect the vaporized gas pressure in the main pipe 6, and a set value, a PID operation is carried out by a main pipe pressure regulating meter 7, and an LNG flow rate setting value signal is found by a carburetor number correcting operator 8, according to the resultant output. And when the condition is tripped by using a single carburetor in a low load condition, a MANUAL mode signal a is given to the main pipe pressure regulating meter 7 by a computer 18, until the waiting carburetors are converted to a load following mode through a rising mode, so as to 'cut' the main pipe pressure control operation, and the output of the main pipe regulating meter 7 is reset to a preset LNG flow rate value.

摘要： PURPOSE:To enable an automatic drive for performing speed control automatically without reducing productivity by unnecessary deceleration and causing an excessive disturbance to a central processing section when a remaining amounts of an inlet side looper and an outlet side looper are controlled in a continuous steel plate processing line. CONSTITUTION:When the remaining amount of the looper is being reduced, a speed setting calculation is performed at a fixed cycle, when a handling work is completed and the remaining amount of the looper increases, the speed of processing of the central section, e.g. of temperature control is accelerated at an acceleration rate to be the largest possible rate of variation of load to return the speed. A computing element 17 calculates a target speed of each coil from a passing condition such as a plate size and required heat cycle and an equipment capacity to be given to computing elements 13, 14 and an intermediate limiter 19. The intermediate limiter 19 checks the upper and lower limits of an output VF of the computing element 15 and calculates and outputs a speed command value VS to be given actually to a motor speed controller 20. The motor speed controller 20 operates a driving motor 23 for a bridle roll 21 so that the line speed takes VS.

摘要： PURPOSE:To make stabilization of quality by compensating the fluctuation in strip temp. by a model error and disturbance, such as change in radiation rate of a strip, with the strip temp. control method for a continuous heat treatment furnace for a continuous annealing line, continuous plating line, etc. CONSTITUTION:The feed forward control to change the setting of heating conditions based on a heat transfer system is executed by the conventional technique at the prescribed timing in the event of a change in strip thickness and heat load, such as target strip temp., in this strip temp. control method. The feed forward control mode is changed over to a feedback control mode by a mode changeover signal (d) by the decision of a process computer 21 upon lapse of the prescribed time. A strip temp. controller 23 makes PID computation in such a manner that the detected value of the strip temp. obtd. from a sheet temp. detector 13 equals to the target value (e) of the strip temp. in the feedback control mode. The controller outputs the same computed signal (f) to computing elements 24 existing by as much as the number of zones. The respective computing elements 24 execute computation and output computed signals (h).
