Claim 6:
7. The method according to claim 4, wherein the control strategy is:
a control strategy of tracking, by the piston of the long hydraulic cylinder, the low-frequency acceleration signal, and simultaneously tracking, by the piston of the short hydraulic cylinder, the target acceleration signal, wherein a reference signal for the long-stroke and low-frequency controller is the low-frequency acceleration signal, and a reference signal for the short-stroke and high-frequency controller is the target acceleration signal; or
a control strategy of tracking, by the piston of the long hydraulic cylinder, the low-frequency acceleration signal, and simultaneously tracking, by the piston of the short hydraulic cylinder, the high-frequency acceleration signal relative to the piston of the long hydraulic cylinder, wherein the reference signal for the long-stroke and low-frequency controller is the low-frequency acceleration signal, and the reference signal for the short-stroke and high-frequency controller is the high-frequency acceleration signal.
