Analysis of Discrete Adaptive Control Technology in Permanent Magnet Brushless DC Motor
This paper expounds the design of a discrete adaptive control algorithm based on parameter estimation.This design derives the discrete mathematical model of BLDCM,estimates system parameters online,designs a discrete adaptive controller,and verifies the discrete PI control and discrete adaptive control algorithms through simulation experiments.The experimental results show that the discrete adaptive control algorithm has good robustness in the case of sudden changes in expected speed and time-varying parameters,and the system overshoot,steady-state error,and adjustment time are all well improved.
