| 中文摘要 |
| 证明Majhi和Atherton(1999)文所提出的改进型Smith预估器等价于一改进的内模控制结构 (IMC), 并对该结构提出一种三阶段设计方法. 为获得扰动抑制和稳定鲁棒性的均衡, 采用了鲁棒控制方法来整定反馈环控制器. 针对某些典型的积分和不稳定时滞过程的设计表明所提方法能获得较好的扰动抑制和稳定鲁棒性的均衡. |
| 英文摘要 |
| A modified Smith predictor proposed in Majhi and Atherto (1999) is shown to be equivalent to a modified internal model control (IMC) structure, and then a three stage design method is proposed for the Smith predictor. To achieve compromise between disturbance rejection and stability robustness, a robust control method is used to tune the feedback loop controller. Design for some typical integrating and unstable processes with time delay shows that the proposed method can achieve good compromise between setpoint tracking, disturbance rejection and stability robustness. |
