摘要
针对同时具有时变状态时滞和时变控制时滞的不确定组合系统 ,设计出基于观测器的鲁棒分散控制器·系统中不确定性为未知时变且范数有界的·根据Razumikhin type理论和Lyapunov稳定性理论 ,获得了系统可鲁棒分散镇定的充分条件 ,最终通过求解 2N个低维Riccati方程来构造相应的控制律 ,适当个数的可调参数既具有灵活性 。
The observer based robust decentralized controller was designed under the condition of the uncertain composite system with time varying states and control delays. The uncertainties are time varying unknown and norm bounded. By using Razumikhin type theory and Lyapunov stability theory, a sufficient condition for the system of robust decentralized stability was obtained. The control law can be constructed by solving 2N low dimension Riccati equations. Proper numbers of parameters are flexible, and easy to be calculated.
