The application provides a parameter setting method of a magnetic suspension bearing, which comprises the following steps: calculating electromagnetic force and acceleration according to current and position in a predetermined time interval; calculating displacement and speed increment according to the acceleration and instantaneous speed; repeating the above steps according to different current and position in a predetermined update number; and finally outputting the displacement to realize parameter setting. The displacement is further calculated according to the electromagnetic force and the acceleration in the predetermined time interval, and the final displacement output is corrected by continuously updating the current and position in different time periods, so that the technical problem of lacking a displacement output method with small result error in the prior art is solved.

The embodiment of the application provides a kind of clamp jaw control method, clamp jaw and storage medium, it is related to automatic control technical field.The specific implementation scheme is: receiving first control instruction, the actual distance between two clamping components is obtained;If the current actual distance is greater than the first specified distance indicated by the first control instruction, and the difference between the reference speed and the instantaneous speed of the clamping component is less than the preset speed, the clamping component is controlled to perform closing motion based on the first control force;If the current actual distance is greater than the first specified distance and the difference between the reference speed and the instantaneous speed of the clamping component is not less than the preset speed, the current second control force is calculated based on the integral of the difference between the reference speed and the instantaneous speed of the clamping component within the current statistical time range, and the clamping component is controlled to perform closing motion based on the difference between the first control force and the current second control force.
