摘要
针对双容液位系统,首先确定了其液位控制的串级控制方案,然后讨论了主副回路的常规PI控制、积分分离的PI控制.此基础上,为了能够适应参考输入信号的剧烈变化并及时提供相应的控制动作,研究了系统的PI加前馈控制.仿真实验结果表明,积分分离的PI加前馈控制方法控制效果良好.
The cascade control scheme of liquid level control was determined targeted double container level system, then the conventional PI control and PI control of integral separation for primary and seeondary loop were discussed. In order to be able to adapt to dramatic changes of the input signal, and promptly provide the appropriate control action, on the basis of the results PI plus feedforward control for system was also discussed. The simulation results show that PI plus feedforward control method of integral separation has a good effect.
