摘要： PURPOSE: To provide a controller for induction motor which is hardly affected by a change in motor constant and an influence by a motor driving condition by reading out the current deviation of the same past voltage vector as an existing voltage vector, and using a predicted current value where it is added to the detected primary current for forming an instantaneous section flux vector. CONSTITUTION: The primary voltage to a three-phase induction motor 8 is detected by a detection means 9a and the primary current is detected by a detection means 9b, and based on these values, a three-phase inverter 7 is controlled by an instantaneous space flux vector forming means 100. At this time, current prediction means 30a, 30b obtain a difference from the detected primary current in the control cycle just before based on the outputted current of a current detector 9b which is a 3-phase/2-phase conversion means to record a current deviation with a voltage vector from a switching table 16 using as a parameter and update it successively. The current prediction means 30a, 30b read out a current deviation with a voltage vector from a switching table 16 using as a parameter and conduct subsequent processing in addition to the outputted current of the current detector 9b.

摘要： PROBLEM TO BE SOLVED: To suppress distortions and cracks of a substrate loaded with chips, by holding at the time of holding the substrate loaded with electronic device chips on a heat radiating plate. SOLUTION: By using magnetic force acting between the permanent magnet 42 of a holding member 40 and a yoke member 44, the substrate 20 loaded with the electronic device chips 10 and 12 is held on the heat radiation plate 30. By holding it in such a manner, the substrate 20 loaded with the chips is held on the heat radiation plate 30, even without having to apply high pressurize on the substrate 20 loaded with the chips. As a result, distortions and the cracks to be generated on the substrate 20 loaded with the chips are suppressed.

摘要： PURPOSE:To obtain a desired amount of power generation effectively by mounting a generator in which the amount of power to be generated is controlled according to a running pattern. CONSTITUTION:In the case of a periodic pattern running, e.g. commutation by a general vehicle or transportation by a business vehicle, a driver turns a switch ON at first and notifies the start of pattern running for a controller 26. The generator output is set equal to a target level, determined based on the output from a motor 10 accumulated for pattern running, during the pattern running after turn ON of the start switch before turn ON of a stop switch. Since power consumption is substantially constant for the pattern running, total power consumption for the pattern running is substantially equal to the amount of power generated by a generator. Consequently, the generator 20 is operated with no fluctuation of load while reducing the harmful components in exhaust gas and enhancing the fuel consumption.

摘要： PURPOSE:To prevent the generation of a torque hunting when a vehicle speed pulse is used instead of a number-of-revolutions pulse. CONSTITUTION:A latest torque command TN is compared with a previously calculated torque command Told thereby to calculate a torque command change DELTAT in the step 112. The calculated torque command change DELTAT is compared with a threshold value DELTATref, and a torque command T value is limited based on its result in steps 114-120. Since the change of the command T of its output is suppressed, a torque hunting is suppressed. Further, the command T is limited by using a map B having a small maximum output torque TmaxB at the time if using a vehicle speed pulse in the steps 124 and 126. Safety in a high speed range is improved. Further, a current command I or a current value is limited. An element damage is prevented.

摘要： PURPOSE:To make it possible to form an environment of driving being fit for the feeling of a driver. CONSTITUTION:ECU 20 recognizes a vehicle speed from the number of revolutions of a motor 14. In accordance with this vehicle speed, a generator controller 28 changes a chopping frequency of a field current supplied to a field coil 24a. Thereby noise corresponding to the vehicle speed can be generated without producing an adverse effect on the efficiency of power generation and also the number of revolutions of an engine can be changed in accordance with the vehicle speed. On the occasion, the number of revolutions of the engine is changed in a high-efficiency area wherein the efficiency of the power generation of the engine does not change nearly at all. Therefore the noise can be changed in accordance with the vehicle speed without having any adverse effect on the power generation.

摘要： PURPOSE:To return the number of revolution of an engine to the range of an objective number of revolution by setting the objective power of a generator so that the number of revolution of the engine becomes the specified number of revolution, and correcting the amount of fuel injection when the target power is deviated from the specified range and the number of revolution of the engine is located at the outside of the range of the objective number of revolution. CONSTITUTION:A controller operates the generated power based on the output current of a generator and operates the objective power based on the number of revolution of an engine. The results are outputted as a control voltage Vs and an objective voltage Vp. Vs and Vp are compared with a comparator. The duty ratio of a power transistor is controlled so that both voltages agree. Then, the number of revolution is inputted (118) into the controller, and whether N is within the specified range or not is checked (120). When N is located at the outside of the range and higher than a reference number of revolution No, a specified voltage value DELTAV is added to Vp (122). The generated power is increased, and N is decreased. When N is located at the outside of the range and lower than No conversely, V is subtracted from Vp (122), the generated power is decreased and N is increased.

摘要： PURPOSE:To provide motor controller for electric automobile in which a clutch and a motor can be protected appropriately even when clutch operation is carried out similarly to an engine vehicle. CONSTITUTION:Upon disconnection of a clutch 21, torque command value for a motor 17 is lowered by an amount corresponding to the difference of friction between a normal engine and the motor 17 to decrease the number of revolution of the motor 17 before the clutch 21 is connected. When the motor 17 has been driven at a speed higher than a number of revolution prescribed for vehicle speed, torque command value is controlled to drop below a predetermined level thus decreasing the number of revolution of the motor 17 below a prescribed level before the clutch is connected. The clutch 21 and the motor 17 are protected by avoiding connection of clutch under a state where the motor 17 has high torque and high number of revolution.

摘要： PURPOSE:To enable the warming-up of an engine by the effective use of exhaust heat without shortening travel distance per charge. CONSTITUTION:At the cold time of an engine 10, the exhaust heat of a power controller unit 16 and a motor 18 is supplied to the engine 10 by the valve control of a cooling pipe. The warming-up of the engine 10 is accelerated by the effective use of heat. The power consumption of a battery 14 is economized, and travel distance per charge is secured. Since the warming-up of the engine 10 is terminated early at the cold start time, harmful components in exhaust gas are reduced.

摘要： PURPOSE:To prevent insufficient acceleration due to consumption of battery. CONSTITUTION:Only when torque is zero, voltage of a battery 10 is taken in through a voltage sensor 15 and a current command is calculated and then outputted. During an interval when the torque is being produced, the battery voltage at the time of zero torque is maintained and control is executed based on thus maintained battery voltage. Since the current command value is determined while following up battery consumption, insufficient acceleration does not occur. Furthermore, since the battery voltage is detected only when the torque is zero, variation of voltage due to battery consumption can be reflected accurately on the control.
