Summary:To accelerate the dynamic convergence speed of the permanent magnet synchronous motor (PMSM) control system and enhance its ability to resist fast time-varying disturbances, a novel sliding mode control method is proposed by constructing switching gain with the system state information and environment information. Firstly, employing the extended state observer (ESO) to estimate and compensate for low-frequency disturbance, thereby effectively reducing the upper bound of disturbance impacting the system. Secondly, the fuzzy system is constructed by using the rate of speed error change and high-frequency disturbance change. The fuzzy system output and the estimate of high-frequency disturbance generate adjustable switching gain, which ensures disturbances is suppressed in time and the small chattering amplitude when the system is running dynamically. The stability of the system is proved by using the Lyapunov theory and the effectiveness of the proposed method is verified by numerical simulations and platform experiments.
