给出了能够实时计算的平衡流形展开模型,分析了平衡流形展开模型由调度变量引入的“隐含耦合”给模型带来的影响,指出了分段线性化模型改变了系统平衡点动态特性的本质。分析了平衡流形展开模型的误差,给出了调度变量的确定方法。

Expansion model based on equilibrium manifold was proposed for real-time calculation. ＂Hidden coupling terms＂ of expansion model based on equilibrium manifold for SISO nonlinear system was studied, and the dynamic parameters＇ change of piecewise linear model was analyzed. The error of expansion model and the method of getting scheduling variable were proposed.
