摘　　要：在分析了系统脉冲响应的Lipschitz指数与线性系统阶次之间的关系的基础上,提出了利用连续小波变换进行线性时不变系统脉冲响应信号奇异性检测的模型阶次辨识的新方法,理论分析和仿真实验说明了该方法的有效性.The relationship between the Lipschitz exponent of impulse response of system and the order of linear TI system is analyzed. A new method based on CWT to detect the singularity of the impulse response of linear TI system is proposed here to identify the order of the system. The effective of the method is proved by theory and the simulation results.
