摘　　要：研究了一类基于事件触发机制的时变时滞网络控制系统的鲁棒H∞保性能控制问题。首先,针对具有时变时延的网络控制系统,为了有效降低网络通信信道中数据的传输量,建立了包含事件触发机制的系统模型。其次,结合Lyapunov稳定性定理,运用Jensen积分不等式和互逆凸组合的处理方法进行稳定性分析,得到了保守性更小的稳定性判据,并结合锥补线性化算法为系统设计了鲁棒H∞保性能控制器。最后,编程和仿真典型的数值实例,并分析其所得结果,从而验证了所使用方法的有效性。The robust H∞ guaranteed performance control problem of time-varying delay network control systems based on event triggering mechanism is discussed. Firstly, aiming at the networked control system with time-varying delay and for effectively reducing the amount of data transmission in the network communication channel, a system model including event triggering mechanism is established. Then combined with the Lyapunov stability theorem, the Jensen integral inequality and the reciprocal convex combination processing method are applied to analyzing the stability, and thus a less conservative stability criterion is obtained. Then a robust H∞ guaranteed performance controller for the system is designed in combination with the conical complement linearization algorithm. Finally, a typical numerical example is programmed and simulated, and the results are analyzed, and all these indicate the effectiveness of this method.
