一类非线性时滞系统的T-S自适应鲁棒控制

T-S Adaptive Robust Control for a Class of Nonlinear Time-delay Systems

非线性时滞系统难以建立精确的数学模型,而且还常伴有不确定性,所以传统的依靠数学模型分析和控制系统的方法很难奏效。针对非线性时滞系统的上述特性,提出了将T-S模糊控制与自适应鲁棒控制相结合的控制策略,利用T-S模糊模型将非线性系统局部线性化,而自适应鲁棒控制可以在保证系统全局稳定的前提下较好地解决时滞给系统带来的不确定性。通过MATLAB仿真分析,验证了该控制策略的可行性和有效性。

It is difficult to establish accurate mathematical models for the nonlinear system with time-delay, and it al- so often accompanied by uncertainty, so it is hard to depend on the traditional method of mathematical model analy- sis and control system. According to the characteristics of nonlinear time-delay systems, this paper presents the con- trol strategy of T-S fuzzy control and adaptive robust control combination, T-S fuzzy model can make the local linear- ization of nonlinear systems, and the adaptive robust control can guarantee the system global stability under the premise and solve the uncertainty caused by the delay. and effectiveness of the control strategy. Through MATLAB simulation analysis, verify the feasibility
