摘要
纯滞后对象是一类很难控制的对象;针对纯滞后对象,提出一种状态反馈优化控制方法;系统的设计方法包括:用高阶分时模型来逼近纯滞后环节;以新型高阶Butterworth最优传递函数为目标函数来设计状态反馈增益阵和状态观测器;仿真结果表明该方法设计的系统具有较高的鲁棒性和抗扰性能。
Plants with pure time delay are diffieuh to control. For plants with pure time delay , a method of optimal control based on state feedback is presented. This method firstly deduces high order model devided by time to approximate pure time delay, then uses high or der Butterworth optimal transfer function as object function of the system to design the gain matrix of state feedback and slate estimator. The simulations show that the system designed by the method is provided with high--robustness and anti--jamming.
