This paper solves the finite-time decentralized control problem for uncertain nonlinear large-scale systems in nonstrict-feedback form. The considered controlled plants are different from the previous results of finite-time control systems, which are the nonstrict-feedback large-scale systems with the unknown functions consisting of all states, interactions, and immeasurable states. Fuzzy logic systems and a filter-based state observer are utilized to model uncertain systems and deal with the immeasurable states, respectively. By combining the backstepping recursive design with Lyapunov function theory, a finite-time adaptive fuzzy decentralized control approach is raised. It is testified that the developed control strategy can guarantee that the closed-loop signals are bounded, and the outputs of systems have satisfactory tracking performance in a finite time. A quadruple-tank process system is given to testify the effectiveness and applicability of the proposed approach.

非严格反馈非线性大型系统的有限时间滤波器分散控制


本文解决了非严格反馈形式的不确定非线性大系统的有限时间分散控制问题。所考虑的受控对象与以往有限时间控制系统的结果不同，有限时间控制系统是具有由所有状态、相互作用和不可测状态组成的未知函数的非严格反馈大规模系统。模糊逻辑系统和基于滤波器的状态观测器分别用于对不确定系统进行建模并处理不可测量的状态。将反推递归设计与Lyapunov函数理论相结合，提出了一种有限时间自适应模糊分散控制方法。实践证明，所开发的控制策略能够保证闭环信号有界，系统输出在有限时间内具有满意的跟踪性能。给出了四罐工艺系统来验证该方法的有效性和适用性。
