摘　　要：阐述基于参数估计的离散自适应控制算法的设计。该设计推导BLDCM的离散数学模型,对系统参数进行在线估计,设计离散自适应控制器,通过仿真实验对离散PI控制和离散自适应控制算法进行验证。实验结果表明,在期望转速突变、参数时变情况下,离散自适应控制算法具有较好的鲁棒性,系统超调量、稳态误差和调节时间都有较好改善。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.
