The invention provides a high-speed buffer based on multi-piezoelectric cooperative friction and a control method. The high-speed buffer comprises a synchronous rotating mechanism and a buffering mechanism. The synchronous rotating mechanism comprises a push-pull rod, a sliding mechanism, a screw rod and a main shaft; the buffer mechanism comprises piezoelectric ceramics, a friction block and a friction driving wheel; when buffering operation is executed, the push-pull rod drives the sliding mechanism to linearly slide when bearing axial pressure, then the sliding mechanism drives the lead screw to rotate, and rotating torque is transmitted to the main shaft and the friction driving wheel. And the friction force between the friction block and the friction driving wheel is controlled by controlling the output signal of the piezoelectric ceramic, so that the rotating speed of the friction driving wheel is controlled.
