非线性是系统中普遍存在的现象,对于非线性控制系统的研究是很有必要的.针对非线性网络串级控制系统,提出一种新的控制器的设计方法.首先建立一个网络串级控制系统的模型,将副被控对象看作一个特殊非线性系统-Lurie 系统,研究其副回路存在网络诱导时延时的系统稳定性问题,然后利用Lyapunov-Krasovskii 的相关理论给出系统稳定的充分条件和设计相应的控制器,最后,通过数值例子来说明所提出的方法的可行性与有效性.“,”The nonlinearity of the systems is a universal phenomenon, so it is imperative for us to learn the nonlinear systems. A new controller design method is proposed for the nonlinear cascade control systems. Firstly, we need to make a model of networked cascade control systems, problem of the stability of the networked cascade control system with its secondary plant being a special class of nonlinear systems--Lurie system is studied in this paper. Considering a network-induced delay in the secondary loop of networked cascade control systems, then a controller design method and a sufficient condition for this system are obtained by using Lyapunov-Krasovskii method. Finally, a numerical example is given to illustrate the feasibility and effectiveness of the proposed method above.
