高阶系统的奇异摄动模型的平衡降阶

Singular perturbation balanced reduction method of high order systems

针对目前比较成熟的奇异摄动模型的平衡降阶方法,提出采用时矩输出拟合来改善降阶系统输出响应逼近程度的改进方法,从而使简化模型具有输出误差小、计算简便等优点,通过给出的实例仿真证实了这一点。

In view of the ripe model reduction methods, such as singular perturbation balanced reduction method, the approach to improve the approximation level of the reduced system is provided. The simulation results show that this method can reduce the output error, more easy and convenient for computation.
