Abstract
Centered on the non-parallel distribution compensation (non-PDC) control scheme, this paper attempts to tackle the issue of event-triggered local stabilization for nonhomogeneous Takagi–Sugeno (T-S) fuzzy Markov jump systems (FMJSs) that take mismatched fuzzy basis functions (FBFs) into consideration. With this aim, this paper presents a framework for formulating local stabilization criteria built on fuzzy Lyapunov functions, establishing criteria for defining an attraction region within an invariant ellipsoidal set and incorporating the occurrence of energy-constrained disturbances into the local control problem. In addition, the mismatch problem encountered in designing an event-triggered fuzzy controller is resolved by integrating a congruent transformation matrix that relies on mismatched fuzzy basis functions while preserving the dependence of the Lyapunov function on the original premise functions. Furthermore, to simultaneously cope with complex and diverse system parameter constraints, a systematic and less conservative method is proposed, which involves centralizing nonhomogeneous transition probabilities (TPs), transforming mismatched fuzzy basis functions into fuzzy basis function errors, and employing relaxation techniques.
本文以非并行分布补偿(non-parallel distribution compensation, non-PDC)控制方案为中心,研究了考虑不匹配模糊基函数(FBFs)的非齐次Takagi-Sugeno (T-S)模糊马尔可夫跳变系统(FMJSs)的事件触发局部镇定问题。为此,本文提出了一个框架,用于制定基于模糊Lyapunov函数的局部稳定准则,建立了在不变椭球集中定义吸引区域的准则,并将能量约束扰动的发生纳入局部控制问题。此外,在保持Lyapunov函数对原前提函数的依赖关系的同时,通过对依赖于不匹配模糊基函数的全等变换矩阵进行积分,解决了事件触发模糊控制器设计中遇到的不匹配问题。在此基础上,针对复杂多变的系统参数约束,提出了一种集中非齐次转移概率(TPs)、将不匹配模糊基函数转化为模糊基函数误差并采用松弛技术的系统、低保守性方法。
