摘要
针对空射巡航导弹从空中发射到实现对地攻击,整个过程高度跨度大、模型参数变动比较剧烈的问题,以及BTT控制对侧滑角的要求,使用H∞/混合灵敏度设计方法,将导弹飞行过程中的参数变动描述为模型输出端的乘型不确定性,基于导弹的三通道解耦模型进行控制器设计。仿真结果表明:设计的控制器能够保证巡航导弹在整个飞行弹道上对于选取的不同特征点均具有较强的稳定性和良好的时域响应性能,并有效地抑制转弯过程中的侧向过载,达到限制侧滑角的目的。
For the large height span and dramatic changes in the model parameters of airlaunched cruise missile during the whole process from launching to hitting ground target,and the request for sideslip angle of BTT control,using H∞ / Mixed sensitivity design method,this paper describes the parameter variations as multiplicative uncertainty in the output,the robust controller is designed based on three-channel decoupling model of the missile.The simulation results show that the designed controller is able to ensure strong stability and well time-domain response performance to the selected different characteristic points throughout the flight trajectory of cruise missile,inhibit lateral overload effectively in the process of turning,and achieve the goal of limiting sideslip angle.
