针对一类线性时变系统提出一种状态反馈镇定控制器设计方法,该反馈控制器能将线性时变系统转化为一个稳定的定常闭环系统.借助线性系统的特征结构配置参数化方法,得到含待求参数的控制器解析形式,并给出控制器的可解性判据.在满足可解性的基础上,进一步对控制器进行了多目标优化改计,使其在保证系统稳定性的同时,具有良好的鲁棒性和干扰抑制能力.通过一个时变卫星姿态控制系统的实际设计表明了该方法的有效性.
A kind of state feedback stabilization controller design method is proposed for a class of linear time-varying systems. The feedback controller can transform the linear time-varying system into a stable stationary closed-loop system. With the help of the parameterized method of the configuration of the linear system, The analytical form of the controller to be solved is given and the criterion of solvability of the controller is given.On the basis of solvability, the controller is further optimized for multi-objective reengineering to ensure the stability of the system At the same time, it has good robustness and interference suppression ability.The effectiveness of this method is demonstrated by the actual design of a time-varying satellite attitude control system.
