扩展状态空间预测控制

基于过程的扩展状态空间模型，导出了一种具有类似离散ＰＩ最优调节器结构并具有未来Ｐ步设定值前馈控制的新型预测控制器．由于其目标函数中考虑了系统状态的变化，因而控制效果要优于仅考虑预测输出误差的情况．仿真结果还表明它优于经典离散ＰＩ最优调节器。

Extended State-Space Predictive Control

Based on the extended state-space model,a new predictive controller with a similar structure of PI optimal regulator and with p-step setpoint forward control is developed.Because of the changes ofthe system state variables having been taken into account in the objective function,its control performance is superior to that of the controller designed by only using the predictive output errors.Thesimulation results also show that the proposed controller is superior to the discrete PI optimeal regulator,
