摘要
针对目前比较成熟的奇异摄动模型的平衡降阶方法,提出了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更小、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, this paper adopts output approach method to improve the approximation level of the reduced system, the simulation results showed that this method can reduce the output error and be more easy and convenient for computation.
