A permanent magnet synchronous motor (PMSM) is a nonlinear, strongly coupled, controlled object with time-varying, fractional-order characteristics. It difficult to achieve the ideal control effect by using traditional method when parameter changes and load perturbations occur during operation of PMSM, so adaptive fuzzy backstepping proposed improve system’s fast response anti-jamming ability in case sudden rotational speed, other conditions. Initially, fractional order theory introduced, utilized decompose system into multiple subsystems, order-based Lyapunov function designed for each subsystem ensure stability. Suitable laws, as well are derived through rigorous mathematical derivation. Finally, controller (FOAB-FPID) combining advantages control. Then mechanical simulation model PMSM established verify validity controller, followed three sets comparative experiments: PID, PID (F-PID), integer-order (IOAB-FPID), which selected simulate under four controllers. it validated on constructed experimental platform. Simulation results show that FOAB-FPID can adaptively adjust parameters speed changes, real-time tracking, maintain stability internal uptake. Compared strategies, reached has better acceleration, performance, anti-disturbance ability, proves rationality effectiveness method.
