摘　　要：针对单调阶跃响应的单变量系统，提出一种基于简化模型的自适应预测控制算法。该算法只需辨识一个参数，大大减少了计算量。从理论上证明了它可保证闭环系统的全局渐近稳定和收敛，并定量给出了预测水平的选择范围。仿真表明此算法是有效的，甚至在时变环境下也能很好地工作。In this paper, an adaptive predictive control algorithm based on a simplified model is proposed for a stable system with monotone step response. There is only one parameter required to be estimated, and hence greatly computational effort can be reduced. It is proved that globally asymptotical stability and convergence of the resulting closed-loop system are guaranteed by the range of the prediction horizon. Simulations show that it is efficient and works well even in time-varying environment.
