中文摘要: 控制系统与网络通讯系统的集成使得对网络化控制系统的研究成为当前控制理论与工程中的一个热点研究问题。另一方面,在网络化控制系统中,由于系统性能的要求越来越高,导致利用传统的线性系统设计方法不能满足系统设计要求。为此,本项目将针对非线性网络控制系统的特点提出系统分析与综合的新思想和新方法,具体内容包括:利用非线性系统建模的有效工具T-S模糊模型,在考虑网络诱导因素时对非线性网络控制系统的建模展开研究;基于多随机Lyapunov函数方法对非线性网络控制系统的稳定性分析展开研究;结合非线性预测控制方法,考虑模型中的不确定性,对非线性网络控制系统的鲁棒控制器及最优控制系统设计问题展开研究,最后搭建实时的非线性网络控制系统平台对所提出的方法进行仿真验证。该项目的相关研究成果将进一步丰富和完善网络控制系统的理论体系,形成具有创新性的科学研究方法,提高非线性网络控制系统在工程实践中的应用能力。

英文摘要: The study of networked control systems becomes a hot research problem in control theory and engineering currently for the integration of control systems and the networked communication systems. On the other hand, in the networked control systems, the use of traditional design methods of linear system can not meet the requirements of the system design due to the demand is higher and higher. Therefore, the new ideas and new methods of nonlinear networked control system analysis will be presented in the light of the characteristics of nonlinear networked control systems. Specifically, in the framework of T-S fuzzy model, a mixed model of nonlinear networked control systems considering the network induced factors and nonlinear will be given. Stability analysis will be done based on multiple stochastic Lyapunov function method. The design of robust controller and the optimal control will be done based on nonlinear predictive control method by considering the uncertainty in the model. A real time platform for simulation of all the proposed algorithms for nonlinear networked control systems will be constructed. This research will further enrich the theoretical system of networked control system and form innovative scientific research methods, and improve the nonlinear networked control systems modeling and applicatio
