摘要
研究了永磁同步电机(Permanent Magnet Synchronous Motor,PMSM)的周期事件触发滑模控制问题。为了节约通信资源,采用周期事件触发机制来决定是否将状态通过网络发送到控制器。首先基于传统的事件触发机制设计了滑模控制器,通过设计事件触发条件,给出了实际滑模存在的充分条件,并证明了系统的鲁棒实际稳定性。在此基础上,提出了一种周期事件触发滑模控制方法。结合周期事件触发机制的特点,估计了相邻两次采样时刻之间误差的上限。通过适当地选择控制增益,给出了选择采样周期的方法,保证系统的鲁棒实际稳定性以及实际滑模的存在性。最后,Simulink仿真验证了本文设计的周期事件触发滑模控制器的有效性。
This paper investigates the periodic event-triggered sliding mode control(SMC)of the permanent magnet synchronous motor(PMSM).The periodic event-triggered mechanism is introduced to schedule the transmission of the system state from sensors to the controller for saving communication resources.Firstly,the sliding mode controller is synthesized based on the traditional event-triggered mechanism.By designing the event-triggered conditions,sufficient criteria for the existence of the actual sliding mode are given,and the robust actual stability of the controlled system is guaranteed.And then the SMC problem is further considered for the periodic event-triggered scheme.By considering the characteristics of the periodic event-triggered mechanism,the upper bound of the error between two adjacent sampling times is estimated.The selection criteria of the sampling period and the control gain are provided for ensuring the robust actual stability of the controlled system and the existence of the practical sliding mode.Finally,simulation results illustrate the effectiveness of the proposed controller.
