摘要：针对一类时滞不确定系统存在有界不匹配扰动,但上界值未知的情形,通过估计不确定性的上界,基于估计值设计了控制器,保证了闭环系统一致有界意义下的鲁棒稳定性,给出了闭环系统鲁棒稳定的充分条件。仿真实验结果验证了结论的正确性。
For a class of time-delay uncertain systems with bounded unmatched perturbations in which the upper bounds of the uncertainties are unknown, robust controllers are designed based on the estimated values, to guarantee the robust stability of the closed-loop systems up to uniform ultimate boundedness. Sufficient condition is given to ensure robust stability of closed-loop systems. Simulation result verifies the correctness of the conclusion.
