摘 要:通过构造新型目标函数,并且采用加权预测控制律代替一步预测控制量,得出了一种具有比例加积分结构的自适应模型算法加权控制器.该控制器能实现无偏差跟踪参考输入轨迹.仿真结果表明,对于时变对象,新算法自适应控制比基本型模型算法控制具有更强的鲁棒性。
Abstract: In this paper, through structuring new objective function,and applying the weighted input instead of single step predictive input,an adaptive model algorithmic controller with proportional-integral(PI) construction and weigthed input is presented.This controller can eliminate steady state tracking error.Simulation shows that the strategy has stronger robustness than basic type model algorithmic control for time-varying process.
