摘要： PURPOSE:To suppress a temperature change to disturbance to be regularly repeated during a repeated operation at the same set value by providing a control input generator to calculate the updated value of a control input from the output of a paired opposite system and the control input of an advanced cycle. CONSTITUTION:A temperature controller controls a temperature (y) in a furnace 1 with heater to be repeatedly operated according to a temperature set value (r) of a prescribed operation pattern by an operation signal (u) from a controller 12 to a heater, and when a temperature set value r(k) is not inputted, a control input generator 10 calculates the updated value of a control input (r') from an output v(k) of a dual system 9 and a control input r'(k) of the advanced cycle in case that deviation e(k) between the temperature set value r(k) and a temperature y(k) in the furnace is inputted to the paired system 9 of an enlarged system 40 in the order of n-1, n-2 starting from k=n. Thus, even in respect to the disturbance with regular repeatability to periodically put in/out a worked object to the furnace, the temperature change caused by the disturbance can be suppressed.

摘要： PURPOSE:To quickly attain a prescribed operation pattern by retrieving the initial value of the adjustment input from the precedent result and not setting the initial value at zero. CONSTITUTION:The initial value of the adjustment input (r') is not set at zero but uses the final value obtained in the precedent operation having an approximate operating environment. A retrieving device 15 retrieves an operation pattern R, for example, and the temperature is raised up to 80 deg.C from 0 deg.C between the 80th and 120th samples. Then the 10th repetitive furnace temperature and the final adjustment input value are retrieved to the prescribed pattern R. The retrieved final adjustment input value is used as the initial value in order to control the pattern R. As a result, the satisfactory follow-up performance shown by a solid line is obtained just with the repetition, i.e., the learning of only twice.

摘要： PURPOSE:To obtain a learning and controlling device without receiving any affection of the saturation of control factors by a method wherein a difference with respect to a given division in an operating pattern is nullified upon learning a regulating input by inputting a difference between the set value of temperature and the measured value of temperature in a furnace and employing a relative system output in accordance with said difference. CONSTITUTION:A memory 11 for a regulating input stores the row of regulating inputs (r') impressed sequentially on an expanding system, consisting of a furnace 1 and a controller 12, in synchronized with the set value (r) of the temperature at every one cycle of an operating pattern. A regulating input generator 10 operates the renewal value of the regulating input (r') from the output (v) of a relative system 9 and the regulating input (r') when a difference (e) between the set value (r) of temperature and the temperature (y) in a furnace is impressed. Then, an output converter 20 nullify the difference (e) with respect to a given division in the operating pattern. The output converter 20 is provided with a function of replacing a part, corresponding to the given division, in which the difference (e) is to be nullified in the furnace temperature (y) in a memory 6 for output, with the set value (r) of temperature in the given division.

摘要： PURPOSE:To change the furnace temperature in accordance with a prescribed operation pattern without using a furnace temperature sensor by collecting the furnace temperature with control of the heater temperature, furthermore performing the learning control for repetition of the operation pattern CONSTITUTION:When the direct control is applied to the furnace temperature (y), this temperature (y) is written in a state memory 20 together with a stale variable (x). At the same time, a switch SW1 of a furnace temperature sensor 3 is closed. Then the temperature (y) is controlled with the output of a direct controller that is obtained when the variable (x), the temperature set value (r) stored in a set value memory, and the adjustment input (r') stored in an adjustment input memory 11 in response to the value (r) are inputted to the direction controller. If a direct control mode is selected for the furnace temperature, the heater temperature measured in a switching state and stored in the memory 20 is set to a heater temperature set memory 21. Then the heater temperature is controlled with the output obtained when the latest state variable (x) and the set value (x) of the memory 21 are inputted to an indirect controller 12a. Thus the effective control is attained for the temperature of a multi-section furnace.

摘要： PURPOSE:To attain quick initial locking of phase control and stable phase automatic control by providing a loop switching device opening a loop switch at starting possible for phase control and controlling this device by a CPU. CONSTITUTION:The loop switch 9 is opened at starting, a control voltage initial value of a voltage controlled oscillator 3 is written in a port 12, its initial value is D/A-converted 13 and becomes a control input of the oscillator 3. Further, an output of an A/D converter 10 representing an output of a phase comparator 7 is fed to a CPU 14 via a port 11 and stored in an RAM 16. Whether or not the phase state stored in this RAM 16 is in the phase locking range is discriminated by a CPU 17. When the phase state is not within the locking possible range, a new control voltage value is set to the port 12 and becomes a control input to the oscillator 3 while being D/A-converted. This operation is repeated until the phase locking range is obtained and when the locking possible range is obtained, the automatic phase control state is attained by allowing the switch 9 to close from the CPU 17 to the port 12.

摘要： PURPOSE:To attain high speed response at the start of reception, stable response at normal reception and quick reply at the time of hitting by providing a sub integrator connected to an output of an absolute circut, a controller connected to an output of a main integration device and the sub integration device and a changeover switch switching the comparator. CONSTITUTION:An output of the absolute circuit 4 is fed to the sub integration device 11, the output of the main integration device 5 and the sub integration device 11 is supplied to the controller 17. A normally open switch 10 is inserted preferably between the absolute circuit 4 and the sub integration device 11. An intial output V0 of a prescribed value generated from the controller 17 and an output of the main integration device 4 are supplied selectively to the comparator 18 by a changeover switch 16. When the controller 17 detects that the output (m) of the device 5 exceeds the initial output V0 of the controller or over, the switch 16 is changed over to apply the output (m) of the main the integration device 4 to the comparator 18 and the time constant of the main integration device 5 is increased sequentially. Thus, the response at the reception start is fast and the reply at normal reception is stable and the reply at the time of hitting is quickened.
