Research on Liquid Level Control Based on Chaotic Optimization Genetic Algorithm in Time Domain Fractional PID Model Prediction

ZHU Qun;ZHUO Shufang;Fujian Polytechnic of Information Technology;  
In order to accurately control the liquid level of the steam generator and ensure the safe operation of nuclear power plant,the time domain fractional order PID model predictive control technology is applied to the liquid level control of the steam generator.Firstly,the basic theory of model predictive control is analyzed,and the mathematical model of liquid level predictive control of the steam generator is discussed;secondly,the design model of fractional order PID controller in time domain is studied;then the time fractional PID model for steam generator level predictive control algorithm designed,and improved ant colony algorithm process of optimizing the controller parameters is designed.Finally,the simulation results show that the time domain fractional order PID control algorithm can get better control effect.
