Decentralized Variable-Structure Control of a Class of LinearUncertain Large-Scale Systems
-
摘要: 研究了具有参数摄动、关联影响和外界干扰等不确定性因素影响的线性大系统的分散控制问题,在假设系统不确定性有界且满足一定匹配条件的前提下,提出了一种分散变结构滑模控制算法,并给出了消颤方案和控制受限的解决方法.该算法结构简单计算量小,同时闭环系统具有较好的动态特性和较强的鲁棒性,数字仿真表明了该算法的有效性.Abstract: The paper proposes a new variable-structure control scheme for a class of linear uncertain large-scale systems with parameter perturbations, interconnections and external disturbances. The chatting and limited control problems are discussed, and proper solving methods are formulated. The proposed control algorithm is concise and easy to be realized, the closed system shows good transient properties and robustness. Simulation results show the effectiveness of the proposed method.
