仿真技术在热工自动控制系统PID参数优化中的应用

Application of Simulation in Automatic Control System PID Parameter Optimization

本文以三级减温控制系统为例,利用响应曲线法获取对象动态特性,在MatLab中构建控制系统仿真模型,成功实现了调节系统PID控制参数的离线优化。由于仿真过程直观高效,此方法可作为其他控制系统PID参数优化的参考。

By taking three-stage attemperation control system as example,using response curve obtain object dynamic performance, simulation system has been constituted in Matlab,off-line optimization of PID control parameter in control system has been success- fully realized.For the simulation is visualized and efficient,it can be used as reference for PID parameter optimization of other control system.
