摘要
永磁同步电机是一个多变量、非线性、强耦合系统,从非线性动态数学模型出发,应用精确线性化理论,实现了永磁同步电机系统的输入-输出线性化与解耦。通过线性化模型设计速度跟踪控制律,用指数滑模变结构控制器来设计电流调节器,算法简单实用,提高了速度跟踪的快速性和精确性。仿真和实验结果表明,该控制策略具有理想的动态性能和良好的鲁棒性。
The permanent magnet synchronous motor is a multi-variable, strong-coupled and nonlinear system. Based on the nonlinear dynamic mathematical model, input-output linearization and decoupling control are achieved by using precision linearization theory. The speed tracking control law is designed from this precision linearization model and the current regulator is designed by the sliding mode variable structure controller. These methods are simple and practical, and improve the celerity and accuracy of speed tracking. Simulation and experiment results indicate that this control strategy achieved ideal dynamic performance and satisfactory robustness.
