摘　　要：针对循环水动态模拟装置中进口温度的控制存在着非线性、大滞后、大惯性和时变性的特点,提出将串级控制和内模控制相结合,并将育种算法用于内模控制器参数的整定,设计出基于育种算法的进口温度ICM-P控制系统。并且通过SIMULINK仿真,将IMC-P控制系统与PID-P控制系统进行比较,结果表明采用基于育种算法的串级内模控制器后,系统的响应曲线超调量最小、过渡时间短、调节品质高,即系统具有很好的快速性和稳定性。According to nonlinear,large lag large inertia and time-varying characteristics of thetemperature control in circulating water dynamic simulation device,Cascade control technology,Intermodel control is analyzed,put forward the viewpoint that combining the two models,and the breedingalgorithm is used for inter model controller parameters setting,design based on breeding algorithm ofinlet water temperature IMC-P controller,by comparing the IMC-P control system with PID-P controlsystem through simulink simulation,the result show that possess minimum overshoot,short transitiontime and high control quality by adapting cascade inter model controller based on breeding algorithm.Inother word,the system has very good rapidity and stability.
