摘要
针对基于经典控制理论导弹稳定控制回路设计时存在的干扰及模型不确定性问题,提出了基于H∞混合灵敏度的导弹稳定控制回路设计方法。通过选取目标函数,将H∞混合灵敏度的问题转化成标准的H∞控制问题,利用Matlab求解了鲁棒控制器,给出了仿真结果。结果表明,利用H∞混合灵敏度方法基于一个特征点所设计的导弹稳定控制回路,对模型不确定性具有较好的鲁棒稳定性,符合系统设计要求。
Aimed at the existent uncertainty of disturbance and model based on missile stability control loop design of classical control theory,the paper proposed a design method of missile stability control loop based on H∞ mix sensitivity.By means of selecting objective function,it transformed the problem of H∞ mix sensitivity as the standard H∞ control problem,and solved the robust controller by Matlab,and then gave the simulation result.The research results show that the designed missile stability control loop based on a feature point by H∞ mix sensitivity accords with the demand of system design,and it owns better robust stability for model uncertainty.
