摘要
针对非自衡对象,为了克服外部不可测扰动,提出了将扰动观测器引入预测函数控制中的方法。即在控制中引入等效的补偿,实现对干扰的完全抑制。并以锅炉汽包水位为控制对象进行仿真。结果表明,系统具有足够的抗干扰能力和良好的动静态特性。
In order to suppress the unmeasurable external disturbance,a novel predictive functional control（PFC） method with disturbance observer for no self-regulating process is presented.By introducing the equivalent compensation to the control,the process can suppress the disturbance absolutely.The boiler liquid level control for feeding water is the typical integral process.The simulation result based on the process shows that the method has better performance in disturbance suppressing,and has good dynamic and static characteristic.
