摘　　要：将现代控制理论的状态反馈及状态观测器 ,引入传统的 Smith预估 PID控制补偿控制 .同时 ,在设计状态反馈及状态观测器中 ,考虑到可能出现的双环谐振情况 .采用基于 Butterworth滤波器原理的协调优化设计方法 .从而 ,改进系统的动态特性 。The concepts of state feedback and state observer in modern control theory are led into conventional Smith predictor and PID control and compensating control. For dealing with resonance of double loop which may occur in designing state feedback and state observer, the design method of coordinated optimization based on the principle of Butterworth is adopted. By which the dynamic characteristics are improved, and the system is provided with good performance and quality.
