Embodiment Construction
[0068] The present invention will be described in further detail below in conjunction with the accompanying drawings: the present embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation is provided, but the protection scope of the present invention is not limited to the following embodiments.
[0069] Such as Figure 1 to Figure 11 As shown, a method for quickly identifying system model parameters based on wide-spectrum excitation signals involved in this embodiment includes the following steps:
[0070] Step 1: Excitation Signal Generation
[0071] At present, the input signals of existing test methods are mostly constant value, constant speed signal, constant speed ramp signal or single-frequency sinusoidal signal, and the spectrum content is single, which cannot meet the full coverage dynamic excitation in the working frequency band of inertial instrument test equipment. Based on this, in the design of the ex...
