摘要
采用改进型的二自由度PID控制器进行温度控制,并提出一种含有早熟收敛判断机制且加入自适应混沌策略的改进型粒子群算法,用于二自由度PID控制器的参数自整定。仿真结果表明,该方法具有良好的控制效果及鲁棒性,适用于吹膜机温度控制系统复杂多变的生产环境。
An improved two degree of freedom PID controller was used for temperature control,and an improved particle swarm optimization with premature convergence judgment mechanism and adaptive chaos strategy was proposed for parameter self-tuning of two degree of freedom PID controller.The simulation results showed that the method had excellent control effect and robustness,and it was suitable for the complex and changeable production environment of film blowing machine temperature control system.
