提出了用PDC跟踪控制器设计飞控系统的方法,给出了稳定性和极点配置定理,将控制器的参数求取问题转化为求解线性矩阵不等式族的问题,所设计的控制器不仅具有全局渐近稳定性,还具有较好的鲁棒性。对用该方法设计的俯仰角跟踪控制器进行了仿真和鲁棒性验证。仿真结果表明,所设计的控制器能够满足性能品质和鲁棒性要求。

Design of tracking controller of flight control system based on T-S model

A method,using the PDC tracking controller,is proposed for flight control system design,and stability determination and pole placement theorems are presented as well.By changing the parameter determination into an LMI group solving problem,the resulting controller shows global asymptotic stability as well as relatively strong robustness.Simulation suggests that a pitch attitude tracking controller,designed by the method above,can meet the performance and robustness requirements.
