摘要： A motion control servo loop apparatus, comprising: a feed-forward control module, and a proportional-integral-derivative (PID) control loop and a compensation adder. The feed-forward control module is capable of generating a feed-forward compensation. The PID control loop further comprises: a proportional control module, an integral control module and a derivative control module. The proportional control module is capable of generating a proportional compensation. The derivative control module is capable of generating a derivative compensation. The integral control module uses a digital differential analyzer (DDA) algorithm to perform integration for accumulated errors with respect to each sampling clock at each DDA pulse and thus output an accumulated error, which is then processed to generate an integral compensation. Thereafter, the compensation adder receives the feed-forward compensation, the proportional compensation, the integral compensation and the derivative compensation to calculate a position error compensation for a motor driver.

摘要： A brushless motor has a stator and an outer rotor. The stator includes a stator core having 6N teeth and 6N coils wound respectively around the teeth where N is an integer equal to or greater than 1. The rotor includes 6N±2 permanent magnets. The permanent magnets are arranged circumferentially around the stator core and face the teeth across an air gap. The radial thickness of the air gap is uneven along the circumferential direction of the motor.

摘要： An adaptive real-time analysis method for dynamic signals generated by rotary machines improves Vold-Kalman filtering order tracing technology to renew the algorithm logic so that on-line computation ability is achieved. Through signal simulation and practical engineering application to verify the availability, it shows that the output results are extremely accurate. As such, this method is advantaged to estimate the time-domain waveform of specific order signals for the operation of the rotary machines and to interpret the related physical phenomena. Moreover, this method can be applied for a digital signal processor (DSP) to obtain real-time and on-line computation of the order signals needed to be traced and to display the tracing time-domain waveform instantly.
