摘要

本文探讨了非线性系统的自适应模糊预定义时间控制问题。文章引入了模糊逻辑系统（FLS）来估计不确定的非线性函数。应用指令滤波器技术克服了 "复杂性爆炸 "的困难。采用误差补偿机制来补偿指令滤波器产生的误差。基于反步进技术，提出了一种模糊自适应预定义时间指令滤波控制方案。所提出的控制策略表明，闭环系统中的所有信号都是有界的，跟踪误差能在预定时间内收敛到接近于零的小范围。仿真结果表明了所开发控制策略的有效性。

Command Filtered-Based Adaptive Predefined-Time Control for Uncertain Nonlinear Systems With Applications to RLC Circuit

This article considers the issue of adaptive fuzzy predefined-time control for nonlinear systems. Fuzzy logic systems (FLSs) are introduced to estimate the uncertain nonlinear functions. The command filter technology is applied to overcome the difficulty of “explosion of complexity”. The error compensation mechanism is adopted to compensate the error generated via command filter. Based on the backstepping technique, a fuzzy adaptive predefined-time command filter control scheme is presented. The presented control strategy demonstrates that all the signals in closed-loop system are bounded and the tracking error can converge to a small area near zero within predefined time. The simulation results illustrate the validity of the developed control strategy.
