条件技术下静态内模控制抗饱和框架稳定性分析

Analysisof Static Internal Model Control Framework's Stability for Anti-windup Based on Conditioning Technique

首先通过MATLAB仿真表明饱和现象给控制系统带来的恶劣影响.在明确发生饱和的本质原因基础上,利用条件技术设计静态内模控制抗饱和框架,并进一步通过仿真实例验证条件技术下的静态内模控制框架的抗饱和效果优于单独采用静态内模控制抗饱和框架.最后利用Popov稳定性判据证明静态内模控制抗饱和框架的全局渐进稳定性.

Static internal model control framework’s stability for anti-Windup based on the conditioning technique is analyzed.MATLAB Simulation demonstrated that how seriously the saturation can bring the influence to the control system.On the basis of knowing the essential of the saturaton,static internal model control framework for anti-windup based on the conditioning technique was proposed.Another example was simulated in MATLAB and the results shows that the framework is more effective for anti-saturation than the single static model control framework.Finally,the global asymptotic stability of the static internal model framwork is proved by Popov stability criterion.
