摘要：为了进一步提高冷轧平整机液压压上系统的动态特性,提出了新的PID参数设计方法:遗传算法.利用Matlab/SIMULINK软件求解优化模型,实现了PID控制参数自整定。对优化得到的PID参数和Z-N整定PID控制效果进行比较,结果表明:遗传算法PID控制优于Z-N整定PID控制,验证了遗传算法的可行性和实用性。
In order to improve the dynamic characteristics of cold rol ing temper mil hydraulic pres-sure system,a new PID parameter control method-genetic algorithm was proposed.By using MATLAB/SIMULINK software to solve the optimization model.the PID control parameter self-tun-ing was achieved.The optimized PID parameters and Z-N tuning PID control effects were com-pared and the results showed that：the genetic algorithm PID control is much better than that of the Z-N tuning PID control.Furthermore,the feasibility and practicality of the genetic algorithm were verified as wel .
