| 摘 要： | 针对一类具有高阶耦合作用的MIMO非线性系统,根据滑模控制原理,并利用模糊逻辑系统的逼近能力,提出一种分散自适应模糊控制器设计的新方案.对每一个子系统,仅通过子系统的局部信息在线调节模糊系统的可调参数、滑模控制增益, 从而实现了对动态不确定性及建模误差进行自适应补偿.理论分析证明了闭环系统是全局稳定的,跟踪误差收敛到零的一个邻域内.仿真结果表明了该方法的有效性.

| Abstract: | A new design scheme of decentralized adaptive fuzzy controller for a class of MIMO nonlinear systems with the high order interconnections is proposed in this paper. The design is based on the principle of sliding mode control and the approximation capability of fuzzy logic systems. The plant dynamic uncertainty and modeling errors are adaptively compensated by adjusted the parameters and sliding mode gains on line for each subsystem using only local information. By theoretical analysis, the closed loop fuzzy control system is proven to be globally stable, with tracking errors converging to a neighborhood of zero. Simulation results demonstrate the effectiveness of the approach. |
