【摘要】：为了提高永磁同步电机位置控制系统在启动阶段位置响应的快速性以及负载扰动时位置响应的鲁棒性,基于分数阶微积分理论,引入状态变量的分数阶积分项,提出一种非线性复合积分滑模面,设计了相应的复合积分滑模控制器,并通过Lyapunov定理证明其稳定性。采用线性二次型调节器方法设计了控制器的参数,并在基于SIMULINK/QuaRC的PMSM硬件在环实时控制系统中,对所提控制算法做了性能测试与对比试验。实验结果表明,所提方法在位置响应的快速性以及对负载扰动的抑制能力方面,优于传统整数阶积分滑模控制方法。
[Abstract]:In order to improve the robustness of position response of permanent magnet synchronous motor (PMSM) position control system in start-up stage and load disturbance, the fractional integral term of state variable is introduced based on fractional calculus theory. A nonlinear composite integral sliding mode surface is proposed, and the corresponding composite integral sliding mode controller is designed. The stability of the controller is proved by Lyapunov theorem. The parameters of the controller are designed by using the linear quadratic regulator method. The performance of the proposed control algorithm is tested and compared in the PMSM hardware real-time control system based on SIMULINK/QuaRC. The experimental results show that the proposed method is fast in the position response and the ability to suppress the load disturbance. It is superior to the traditional integral sliding mode control method.
