Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings. Such as Figure 1-2 As shown, a real-time waveform reproduction control method of an electro-hydraulic servo system includes the following steps:
[0028] A. Set the position waveform signal to be reproduced as position reference signal 1;
[0029] B. Use the position input signal 9 of the electro-hydraulic servo system 3 as the position input signal 9 of the adaptive filter I5, and calculate the position output signal of the electro-hydraulic servo system 3, that is, the response signal 4 and the position output signal of the adaptive filter I5 Difference;
[0030] C. Based on the difference between the position output signal 4 of the electro-hydraulic servo system 3 and the position output signal of the adaptive filter I5, use the RLS adaptive filter algorithm 12 to adjust the weight of the adaptive filter I5 online in real time to perform electro-hydraulic servo sys...
