摘要：Due to the position tracking problem of linear stepping motor, a fuzzy controller is designed with observer and finite-time prescribed performance, which can improve the transient and steady-state performance of tracking error at finite time. Through the d-q state equations of linear stepping motor, the proposed control scheme is carried out by using backstepping method. To deal with the unmeasurable problem of motor states, an efficient observer is designed. In addition, it is not required to contain the known functions of motor state equations in the control law of the proposed scheme, which makes the control scheme more flexible. Based on Lyapunov stability analysis, it is proved that all the signals in the motor closed-loop system are uniformly ultimately bounded. Finally, the effectiveness of the proposed control scheme is verified by simulation.
