摘　　要：为了有效地将连铸机结晶器的液位控制在目标值,解决系统干扰、非线性和时变等因素所造成的建模困难,引入灰狼优化算法GWO对PID控制参数进行优化和自调整,基于连铸机结晶器液位系统的调整时间和稳态误差构造目标函数。仿真结果表明,GWO-PID系统阶跃响应曲线更平滑,超调量为7.08%,小于其余类型的PID控制器;响应速度更快,调整时间为5.03 s,少于其余类型的PID控制器,可以显著提高系统的控制速度和精度。In order to effectively control the liquid level of the continuous caster crystallizer at the target value and solve the modeling difficulties caused by system interference,nonlinear,and time-varying factors,the grey wolf optimization algorithm GWO is introduced to optimize and self-adjust the PID control parameters.Based on the adjustment time and steady-state error of the continuous caster crystallizer liquid level system,an objective function is constructed.The simulation results show that the step response curve of the GWO-PID system is smoother,with an overshoot of 7.08%,which is smaller than other types of PID controllers;the response speed is faster,with adjustment time of 5.03s,less than other types of PID controllers,which can significantly improve the control speed and accuracy of the system.
