摘　　要：针对参数变化、负载扰动带来的永磁同步电机速度控制问题,提出基于投影算法的永磁同步电机模型自适应补偿速度控制。依据永磁同步电机速度环模型自适应补偿的充分条件,设计满足该条件的参数、负载估计投影算法,并以计算出的前馈控制量补偿到速度控制系统中,使实际速度系统等效于无参数变化、无负载扰动的标称模型,并对该标称模型设计速度跟踪控制器。仿真和实验表明,该方法可实现了速度控制系统在参数、负载不确定性环境下的快速、小超调甚至无超调的鲁棒跟踪控制。In order to improve the robustness for load disturbance and parameter variable of permanent magnet synchronous motor（PMSM） speed control, a new model adaptive compensation control based on projection algorithm was proposed in this paper. Firstly sufficient condition satisfied with model adaptive compensation was deducted in detail. Then the projection parameter estimation algorithm satisfied with the condition was designed. Calculation of the estimations feed-forward compensated PMSM speed control system. With the help of on-line adaptive compensation, the real system is equivalent to normal model without load disturbance and parameter variable and the speed controller based on the normal model was designed . Finally simulation and experimental results show that the control strategy has a good robustness for load disturbance and parameter variable, furthermore it can achieve rapid and little overshoot or nonovershoot response performance.
