| 摘 要： | 研究了一类同时具有输入时延和外部干扰的网络控制系统滑模变结构控制问题。首先,通过引入特殊变换将原不确定时延系统转化为无时延系统;然后,在新坐标下,通过模型降阶,结合线性矩阵不等式方法设计滑动模面,并选择控制律保证闭环系统在有限的时间内到达滑模面;最后,对其稳定性进行了分析,给出并证明了原系统渐近稳定的充分条件,并通过数值例子说明了设计方法的有效性。

| Abstract: | In this paper,the sliding mode controller designed for a class of networked control systems with network-induced delay and uncertainties was studied.A particular linear transformation was introduced to convert the original time-delay system into a delay-free form.With reducing the regular systems and the LMI approach,a sliding hyper-plane was designed in the new coordinate system.The proposed control law drived the system to reach the sliding mode in finite time.Finally,a sufficient asymptotic stability con... |
