摘要： An apparatus of controlling an electronically controllable throttle valve for car has a sensor for detecting the opening of the throttle valve and a microcomputer. A throttle valve opening command value is delivered in the form of a digital signal under the control of the microcomputer. The digital command value signal is converted into an analog signal and on the basis of the analog signal and a detected throttle opening, a motor connected to the throttle valve is driven to control the opening thereof.

摘要： The present invention addresses a problem as to how to provide a motor control apparatus which has a magnetic pole position inferring means capable of inferring the position of a magnetic pole of a synchronous motor by adopting a simple method in a short period of time with a high degree of accuracy. In order to solve this problem, a signal id1* for inference use is applied and a peak value iqh of a response current iq' is detected by an iq' peak detecting unit. The peak value iqh is then supplied to a magnetic pole position inferring unit for inferring the position of the magnetic pole of the synchronous motor by carrying out multiplication processing.

摘要： In an a.c. motor control method and apparatus, operations are carried out at a current controller and a voltage setting using interrupt signals generated in synchronism with maximum and minimum values of a carrier wave at a control device for controlling an inverter for driving an alternating current motor. In operations at the voltage setting part carried out using one of the interrupt signals, a carrier wave is corrected in such a manner that phases of voltage command values gradually come into synchronism with a carrier wave. An integral multiple of the period of the carrier wave becomes the period of the a.c. voltage and current control operation timing is carried out in synchronism with the carrier wave.
