Delay-dependent Guaranteed Cost Control for a Class of Large-scale Systems with Time Delays

考虑了一类不确时滞关联大系统的时滞依赖保性能控制,所设计的控制器对于所允许的的不确定参数和时滞,能保证闭环系统渐近稳定且闭环的性能函数值不超过给定上界.最后,通过解优化问题得到性能指标的最小上界.数值例子证明了所设计方法的有效性和具有较小保守性.

This paper considers the delay-dependent guaranteed cost control for a class of uncertain large-scale systems with time delays. For all admissible uncertain parameters and delays, the designed controller can guarantee that the closed-loop system is asymptotically stable and closed-loop cost function value is not more than a given upper bound. Finally, an minimized upper bound is obtained by solving a optimization problem. Numerical example has shown that the designed method is effective and less conservative.
