摘要
针对一类具有输入饱和的连续时不变非线性系统,提出一步输出反馈抗饱和补偿设计.当系统状态满足一定约束条件时,非线性系统可用Takagi-Sugeno模糊模型精确重构.针对重构后的系统,运用并行补偿技术和输出反馈,提出一个含有抗饱和补偿项的一步抗饱和控制方案.基于李雅普诺夫稳定性理论,导出了闭环系统的稳定判据,同时给出了吸引域估计及其优化模型.对一类混沌鲁里叶系统进行仿真实验,仿真结果证明了本方案的有效性.
One-step output feedback anti-windup compensation design for a class of continuous time-invariant nonlinear systems with input saturation was considered.When the system state satisfied certain constraints,the nonlinear system could be reconstructed accurately by Takagi-Sugeno fuzzy model.For the refactored system,using parallel compensation techniques and output feedback,a one-step anti-windup control scheme with anti-windup compensation term was proposed.Based on Lyapunov stability theory,the stability criteria of the closed-loop system was derived,and the attraction domain estimation and its optimization model were presented.Simulation experiment for a class of chaotic Lurie system was given,and the simulation results verify the effectiveness of the proposed method.
