摘　　要：在内模控制的基础之上引入前馈控制,并对反馈回路做了改进。使改进后的前馈-内模控制算法不仅拥有内模控制的优点,而且提升了其抗干扰能力。以热工系统中的主汽温控制为例,由MATLAB仿真结果表明:改进的前馈-内模控制消除干扰的能力比内模控制强很多。Based on the internal model control,the feedforward control was introduced and the feedback loop was improved so that the improved feedforward-internal model control algorithm has advantages of internal model control and strong anti-disturbance ability.Taking main steam temperature control for example,the simulation with MATLAB shows that this improved control outperforms the internal model control in eliminating disturbance.
