摘要
设计了一种基于滑模变结构的永磁直线同步电机(PMLSM)矢量控制系统。从直线电机的基本工作原理出发,通过坐标变换,建立PMLSM在两相同步旋转正交坐标系上的数学模型。基于滑模变结构和李雅普诺夫稳定性理论设计转速调节器,组成PMLSM滑模控制系统。为了验证该控制系统的有效性,在MATLAB/Simulink平台下搭建系统的模型并进行仿真。仿真表明,该控制系统具有很强的鲁棒性。
A permanent magnet linear synchronous motor(PMLSM)vector control system based on sliding mode variable structure was designed.Proceeding from the basic work principle of the PMLSM,and then according to the coordinate transformation,the mathematical model of it is established in the two phase synchronous rotating orthogonal coordinate system.The speed regulator was designed based on the sliding mode variable structure and Lyapunov stability theory,which was composed of the PMLSM vector control system based on sliding mode variable structure.In order to demonstrate the effectiveness of the control system,the model of whole system was built and carried out based on the MATLAB/Simulink.Simulation results verified the control system had strong robustness.
