摘要
DMC在对非自衡对象建模时会产生截断误差 ,因此无法直接用于该类对象控制 .根据非自衡对象阶跃响应的最后阶段可视为直线的特点 ,提出了一种基于对象阶跃响应的参数化模型的预测控制算法 ,该算法避免了 DMC预测模型的截断误差影响 .仿真结果表明 ,提出的算法对于设定值变化具有良好的跟踪性 ,对于模型参数的摄动具有良好的鲁棒性 。
DMC couldn't control integrating plant,because truncated errors would be brought. According to the characteristic that final trend of a step response for integrating plant was line movement, a model predictive control algorithm was presented based on a step response, truncated errors of DMC predictive model could be avoided by use of this algorithm. The results of simulations show,the result of this algorithm follow well the tracks of setpoint , this algorithm have good robust performance for model parameter perturbation,and this algorithm be practicable for integrating plant control.
