摘要
将被控对象零点分解为最小相位项和非最小相位项，并形成新的预测方程，基于ＧＰＣ算法的目标函数，得到非最小相位系统的ＧＰＣ控制算法，保证了在加权系数为零的极限情况下系统的稳定性。仿真结果表明了这一算法的有效性。
The plant model was factorized into minimum and non-minimum phase terms, from which a special type of predictor was formed. Then a new GPC law was developed based on the GPC weighting cost index. The proposed control law ensures guaranteed robustness for non-minimum phase systems even if the control weighting tends to zero. The simulation results shown that it is effective.
