摘要
将改进的自适应逆控制方法应用于永磁同步电机(PMSM)伺服控制系统中,提出PMSM伺服控制系统自适应逆控制策略。针对传统自适应滤波算法的不足,提出变换域变步长NLMS算法,解决非线性时变特性的跟踪控制问题。采用该算法对PMSM伺服控制系统进行控制,仿真结果表明该自适应逆控制方案精度高、跟踪快、鲁棒性较强。
A improving adaptive inverse control system for PMSM servo system was designed. Aiming at shortage of traditional adaptive filter algorithm, a design method of adaptive inverse control was presented, and it transform domain variable step - size NLMS algorithm. The algorithm is used to in controller PMSM servo system, simulation result shows inverse control has the good performance of speediness tracking and strong robust.
