摘要
通过研究线性系统脉冲响应的奇异性和线性系统阶次之间的关系 ,借助于小波变换来确定系统脉冲响应的奇异性指数Lipchitzα ,从而得到了一种确定模型阶次的新方法 .通过理论推导和仿真研究 。
The relationship between the singularity of impulse response of system and the order of linear TI system is analyzed in this paper. It uses the wavelet transform to calculate the Lipschitz α of the impulse response of system, and proposes a new method to identify the order of the system. The effectivity of the method is proved by theory and the simulation results.
