基于H2/H∞复合控制的CMG框架伺服系统参数摄动抑制方法
Parameter Perturbation Suppression Method for CMG Framework Servo System Based on H2/H∞ Composite Control
摘要
Abstract
The Control Moment Gyroscope(CMG)frame servo system is often affected by multi-source disturbance such as external disturbance and internal parameter perturbation,which leads to the reduction of its control per-formance.This paper focuses on the influence of parameter perturbation on the frame servo system,and puts for-ward a perturbation suppression method for CMG frame servo system based on H2/H∞ composite control.Firstly,the motor parameter perturbation is introduced into the conventional H∞ robust control method,which improves the suppression ability of the internal parameter perturbation on the basis of the robustness of external torque perturba-tion.Secondly,combined with the H2 control strategy,the state-feedback-based H2/H∞ composite control method is proposed,which ensures the steady state performance and further improves the dynamic response speed of the system.Simulation results show that the proposed H2/H∞ composite control method can effectively reduce the speed fluctuation caused by multi-source disturbances and improve the dynamic response speed of the system.关键词
