过热蒸汽温度MPC-PID控制系统具有较好的给定值跟随性、抗干扰性和鲁棒性。

Abstract

Based on analyzing features of taking the superheated steam temperature as a controlled object

a model predictive control(MPC) strategy based on the model algorithm control has been put forward

and the basic process of model algorithm as well as MPC-PID cascade control structure being analysed and designed respectively.The emulation program for superheated steam temperature has been worked out by using the MATLAB software

and the emulation study and comparision between the said MPC and the convertional control system being carried out.Results show that the MPC-PID superheated steam temperature control system has better set-point tracking property

anti-interference

and robustness.
