基于H_∞和μ综合的防空导弹鲁棒控制器设计

Robust Controller Design for Antiaircraft Missile Based on H_∞ and μ Synthesis

防空导弹飞行环境复杂,气动参数变化剧烈,使得被控模型存在有界干扰和不确定性参数大范围摄动;以俯仰通道为例,建模分析测量噪声和执行机构的不确定性,分别应用H∞和μ综合方法进行鲁棒控制器分析设计,仿真验证了鲁棒控制良好的动态性能和鲁棒性能。

With the complex flight environment and dramatic changing aerodynamic parameters of the antiaircraft missile,bounded disturbance input and uncertain parameters existed in the control model.Pitching channel was taken for example,modeled and analysed the measurement noise and the uncertainty of actuator servo mechanism,H∞ control and μ synthesis was applied in the analysis and design of robust controller,and the experimental simulation results verified the good dynamic performances and robustness performance of the controller.
