摘要
研究了一类单时滞线性系统变结构控制律的设计方法,基于模糊T-S模型把一类单时滞线性系统化为若干个时滞子系统,然后对时滞子系统设计变结构控制律,取全局控制作为系统的控制律,从而达到对单时滞线性系统系统进行控制的目的,给出了单时滞系统的滑模稳定的条件.仿真表明控制策略的有效性.
The variable structure control design for single time-delay linear systems is discussed. By employing the fuzzy T-S model, the set of single time-delay linear systems can be integrated into a global model that is equivalent to the single time-delay system. Then for each subsystem we design the variable structure control. Based on the fuzzy logic, a global variable structure controller is designed for single time-delay linear systems. The stability of sliding mode is proven. Simulation is presented to show the effectiveness of this control strategy.
