摘　　要：针对永磁同步电机(PMSM)转速调节和估计问题,提出一种无速度传感器的PMSM调速系统.利用双曲正切函数代替符号函数,设计了自适应模糊滑模软切换控制器,实现了软切换连续控制,削弱了抖动现象.通过设计鲁棒无源控制器,得到了旋转坐标系下的u_d和u_q.建立了自适应滑模观测器,并给出了速度辨识律,观测器的增益通过求解线性矩阵不等式得到.仿真结果表明了该控制策略与观测器配合的有效性,且控制系统具有良好的动、稳态性能.In view of the speed regulation and estimation problem of permanent magnet synchronous motor（PMSM）,a speed modulation system based on speed sensorless for PMSM is proposed.The adaptive fuzzy sliding mode soft switch controller is designed by using the replacement of sgn（x） function by tanh（x） function,which realizes the soft switch control and reduces chatting.A robust passivity-based control algorithm is constructed to obtain the u_d and u_q based on the passivity-based control principle.An adaptive sliding mode observer is established and a speed identification law is proposed,and the gain matrix of the observer is obtained by solving linear matrix inequalities.The simulation results show that the proposed strategy is effective,and the system has a satisfactory performance.
