针对一类具有未知非线性死区输入的高阶关联大系统,设计了一种新的分散控制方法。该方法基于模糊滑模控制原理,确保所设计的分散控制器能使各个子系统仅根据自己的信息就能确定相应的控制量,真正实现分散控制。Lyapunov稳定理论分析证明了闭环系统的全局稳定性,跟踪误差收敛到零,并且给出了全局一致终结有界的相关界。仿真结果表明了所设计方法的有效性。
For a class of high-order large-scale interconnected systems with unknown nonlinear dead-zone inputs, a new decentralized control method is designed. The method is based on the principle of fuzzy sliding mode control to ensure that the decentralized controller is designed so that each subsystem can determine the corresponding control amount based on its own information and truly decentralized control. Lyapunov stability theory analysis proves the global stability of the closed-loop system, the tracking error converges to zero, and the bound of the global uniform termination is given. Simulation results show the effectiveness of the proposed method.
