过热汽温串级MCP-PID控制

Superheated Steam Temperature Cascade Control System Based on MCP-PID Control

为提高过热汽温控制品质,尝试将一种新型的PID控制器——MCP-PID控制器应用于过热汽温串级控制系统中。针对一个典型的过热汽温过程,设计了串级的MCP-PID控制器,并利用Simulink仿真平台进行了控制系统仿真试验。仿真试验结果表明,在设定值扰动试验和内外扰动试验中,MCP-PID控制器均优于传统PID控制器,具有超调量小、调整时间短、扰动抑制强和鲁棒性高的特点,值得在复杂工业控制系统中推广应用。

In order to improve the control quality for temperature of superheated steam, the new type of PID controller, i. e. , MCP-PID controller has been applied in superheated steam cascade temperature control system. The cascade MCP-PID controller is designed for a typical superheated steam process, and the simulation test of the control system is conducted by using Simulink simulation platform. The results of simulation test show that in set-point disturbance test and internal and external disturbance tests, MCP-PID controller is better than traditional PID controller, it features small overshoot, short adjusting time and high capability of disturbance rejection and strong robustness, so it is worth to be promoted in complex industrial control systems.
