Fuzzy Sliding Mode Control of Permanent Magnet Synchronous Motor Based on the Integral Sliding Mode Surface

In order to solve the parameter uncertainty, reduce the number of fuzzy rules, and realize the high precision and steady state operation of PMSM under the uncertainty abrupt load torque, this paper proposes a fuzzy sliding mode control method for PMSM based on the integral sliding mode surface. The fuzzy controller in this method is a one-dimensional fuzzy controller, which can realize high precision robust control of the motor with unknown parameters. Simulations and experiments show that this method is superior to other methods in stability.
