Adaptive Control of Permanent Magnet Synchronous Motors with Parameter Changes
Aiming at the current and speed control problems caused by the parameter changes of permanent magnet synchronous motor,an adaptive control strategy based on backstepping method was designed.The mathematical model of permanent magnet synchronous motor under parameter changes was established.The current adaptive controller and speed adaptive controller were designed respectively by backstepping method to improve the robustness of the system to parameter changes.The superiority of the proposed method in dynamic performance and system stability was verified by comparative experiments with traditional cascade PID control.
