| 摘 要： | 针对一类不确定多时滞广义系统,该多时滞广义系统同时具有状态和控制时滞。假设不确定范数是有界的,且系统的状态是完全可测的,通过引进二次稳定性的概念,结合线性矩阵不等式的设计方法,给出了鲁棒非脆弱保代价控制的充分条件。通过对线性矩阵不等式的求解,可得非脆弱状态反馈鲁棒保代价控制器。该控制器对所有容许的不确定性,能保证闭环广义系统的稳定性,而且也能满足二次型代价函数的上界。最后,通过算例仿真表明所提出结论的可行性和有效性。

| Abstract: | The problem on robust non-fragile controller for a class of uncertain singular systems with multiple time-delay is studied. Under the assumption that the uncertainty is norm-bounded and the states of the singular system are available, based on the quadratic stability and method of linear matrix inequality, robust non-fragile guaranteed cost controller for singular systems with multi-time delay is obtained. The controller can make the closed-loop systems asymptotically stable, as well as satisfying the upper-bound of quadratic functions. Finally, simulation results with MATLAB show its feasibility and validity. |
