[0042] Such as figure 1 As shown, the method of suppressing the multi-modal residual vibration of the system based on the S-shape provided by the present invention is detailed as follows:
[0043] Step S1, obtain the multi-modal natural frequency ω of the mechanical system 1 , Ω 2 ,……Ω n ; In a mechanical motion driven by a driving device, the requirements for high speed, high precision and stability are very high. In the process of motion, the first step is to obtain the natural frequency ω under the multi-modality of the mechanical control system. 1 , Ω 2 ,……Ω n , The frequency obtained is different in each stage.
[0044] Step S2, establish a mathematical model for the seven-stage S-type speed planning problem; after obtaining the frequencies of each stage, according to the different frequencies obtained in each stage, establish a seven-stage S-type speed planning problem for the motion of the mechanical control system Mathematical model. In the establishment of the mathematica...
