摘 要: 针对直线开关磁阻电机网络化运行诱导时延及位置跟踪控制等问题,结合系统在线辨识获得电机模型,将网络化直线开关磁阻电机运动控制系统建模为马尔可夫时延系统.提出具有反馈通道时延的网络化直线开关磁阻电机位置跟踪控制方法,利用Lyapunov稳定性定理和线性矩阵不等式技术得到系统稳定的充分条件,给出状态反馈控制器设计.选取4组不同频率和幅值的正弦参考信号进行实验验证,证实该方法是有效可行的. This paper addresses the positioning control for the networked linear switched reluctance motor( LSRM)with network-induced sensor-to-controller time delays. The motor parameters are obtained by online system identification method. The LSRM over communication network is modeled as a Markov time-delay system. The stability conditions and the positioning controller design method for the LSRM are obtained by using Lyapunov theory and inequality technique. Experiments are conducted using four sinusoidal reference signals to verify the effectiveness of the proposed positioning control method for the networked LSRM.
