摘要：

Due to the multi-variable and time-variety characteristic of the permanent magnet AC servo control system, a model-free adaptive control (MFAC) algorithm is proposed on the basis of extended Kalman filter (EKF). The problem of the over-reliance on accurate mathematical model of the controlled system is solved by pseudo-gradient method derived from the input and output information. Moreover, an EKF based observer that has the ability to pre-estimate the parameters accurately is designed. Based on MATLAB/Simulink, the simulation results show that the proposed method can control and track the non-linear system precisely.
