Embodiment Construction
[0060] The present invention will be further described below in conjunction with the accompanying drawings. Such as Figure 1-3 As shown, an ADRC control method for a six-degree-of-freedom electro-hydraulic vibration table, the six-degree-of-freedom electro-hydraulic vibration table includes three horizontal valve-controlled cylinder mechanisms, three vertical valve-controlled cylinder mechanisms, and an upper platform 7 and lower platform 8; the three horizontal valve-controlled cylinder mechanisms are respectively No. 1 valve-controlled cylinder mechanism 1, No. 2 valve-controlled cylinder mechanism 2 and No. 3 valve-controlled cylinder mechanism 3; the three vertically The cylinder control mechanisms are No. 4 valve control cylinder mechanism 4, No. 5 valve control cylinder mechanism 5 and No. 6 valve control cylinder mechanism 6; the No. 1 valve control cylinder mechanism 1, No. 2 valve control cylinder mechanism 2 and No. 3 The outer ends of the valve-controlled cylinder...
