摘要
分析了常规内模控制中存在的缺点,提出了一种基于模型完全动态延时逆的内模控制方法,取消低通滤波器的设计,以逆的延时时间的调整来提高系统的鲁棒稳定性,并结合自适应逆控制原理,采用有效消除被控对象下游输出端和上游输入端扰动的内模控制方法.
This paper analyses the faults existed in general internal model control and puts forward an internal model control method based on dynamic delay inverse of the whole model. The robustness and stability of the control system is improved by adjusting the delay time for inverse that replaces the design for the low-pass filter. The principle of adaptive inverse control is applied and the internal model control method adopted, which effectively cancels the disturbance from output and input of the controlled plant.
