摘要
文章针对被控对象模型参数的时变和非线性特性给风扇直吹式锅炉主汽压力自动调节带来的控制品质恶化问题,采用了一种极点配置自校正PID控制策略,这种控制算法综合了常规PID和自适应控制的优点,具有结构简单、响应快、鲁棒性强等优点,仿真表明这种控制器能有效改善该类系统的控制品质。
A kind of self-tuning PID control strategy is adopted to overcome the problems of the main steam pressure control of boiler brought by time-varying and non-linear characters of controlled process. The algorithm has the advantages of ordinary regulators and adaptive controller. It has the characteristics of simple structure,fast response and strong robustness. The simulation shows that the controller can effectively improve the control performance of the systems.
