基于干扰观测器PID在主蒸汽温度控制系统的应用

Application of PID based on disturbance observer on main-steam temperature control

针对常规PID控制策略很难满足火电厂主汽温度的控制要求,提出了一种基于干扰观测器的PID控制算法,即在1个常规PID控制器的基础之上增加了干扰观测器,以获得满意的控制品质。经仿真研究表明,该方法加快了控制系统响应速度,具有较强的鲁棒性和自适应能力。

Since the conventional PID control fails to meet the requirements of main-steam temperature control in thermal power plant,this paper proposes the PID control based on disturbance observer which is added on the conventional PID controller to require pleasing control quality.Simulation shows that this method accelerates control response and enjoys strong robustness and adaptive capability.
