Finite-time Fuzzy Adaptive Backstepping Control of Permanent Magnet Synchronous Motor Stochastic System

A finite-time fuzzy adaptive backstepping control method is proposed for the position tracking control of PMSM stochastic system in this paper . Firstly, this paper considers the random disturbance of PMSM in operation, and uses the fuzzy logic control method to deal with the random nonlinear function in the motor model. Secondly, the finite-time control is applied to the random nonlinear system of PMSM to improve the convergence speed of the system, control accuracy and anti-interference ability. Finally, the simulation results verify the effectiveness of the proposed control method.
