摘要
以不确定的无自衡大时滞过程为研究对象 ,对常规的 Smith预估控制系统进行变形 ,由模型不确定性得到一个时滞相对小的广义被控对象 ,通过对该时滞相对小的广义被控对象设计控制器来实现对无自衡大时滞过程的鲁棒性控制 .理论分析和仿真结果表明 ,这种新型控制方法不仅能消除大时滞带来的不良影响 ,且鲁棒性强 ,能够有效抑制干扰和模型不确定性 .对无自衡大时滞过程的有效控制提供了新的思路 .
A novel method of robust control is proposed for processes with integrator and long dead time. The conception of a general controlled process derived from model uncertainty is introduced with a new transformation of the normal Smith predictor. A stabilized controller designed on the general controlled process can achieve robust control of the actual process and the selection of controller can utilize many currently available PID tuning rules. The controlled systems can effectively cope with disturbance and model uncertainty. Simulation results proved the feasibility of the method.
