| 摘 要： | 内模控制是一种新型控制算法,它有良好的跟踪性能和鲁棒性,但抗干扰性不够理想。本文把串级控制的思想引入HMC,得到了一个新型控制结构,并给出了一般的设计方法。通过对某电厂主汽温控制系统的仿真表明,这一新型控制方法在跟踪性、鲁棒性和抗干扰性等方面均可获得满意的效果。

| Abstract: | Internal model control(IMC) is a new type control algorithm. It has good tracking performance and robustness, but unsatisfactory response to disturbance. In this paper, the cascade control structure is introduced into the IMC and a new type cascade control scheme combining the IMC and the PID control is presented. The general design method for this new control scheme is given. Simulation results show that the new control method has satisfactory tracking performance, roubustnees, and the ability to suppress disturbance and the new type control is better than the conventional PID cascade control. |
