Path Tracking of Permanent Magnet Synchronous Motor Using Fractional Order Fuzzy PID Controller

Permanent magnet synchronous motor (PMSM) AC servo system has the characteristics of uncertainty, time-varying, nonlinear and fractional order. Applying traditional control method is difficult to achieve desired effect. The fuzzy strong adaptability parameter change, nonlinearity imprecise model controlled object. simulation permanent three closed-loop systems established. principle realization space vector pulse width modulation (SVPWM) are studied by using a strategy. Due fractional-order characteristic motor, logic algorithm used realize self-tuning proportional integral differential (PID) controller. controller selected as position regulator motor. It combines precision PID with adds feed-forward improve response speed. path tracking experiments on several different paths carried out, results show that effective can meet trajectory requirements control. Finally, speed test PMSM out verification platform, which verifies effectiveness algorithm.
