摘要
针对一类不稳定时滞过程,采用双环控制结构,首先使广义对象(内环)稳定,然后根据内模控制原理设计外环控制器,得到等效的PID控制器参数的整定方法.仿真结果表明,整定后的系统不但具有良好的鲁棒性,而且调节快速,适合于工程实际应用.
A double loop structure is employed to a class of unstable process with time delay. After stabilizing the inner loop, design the feedback controller according to the internal model control（IMC） theory, and give out a PID controller. Extensive simulations have shown that the proposed methods can provide not only high robustness, but also reduce settle time for unstable processes.
