Title: Method of gain control for mechanical motion control system with negative feedback
Inventor: SUENOBE KAZUHIRO
IPC: H02P29/00
Filed: 2000-01-24
Abstract: PROBLEM TO BE SOLVED: To provide a method that sets multiple gain parameters which determine fidelity of movement to an instruction and stability for a mechanical motion control system driven by a servomechanism as a drive source with negative feedback, considering the load mass ratio and the load moment inertia ratio (load inertia ratio), and makes an adjustment of a simple gain control by a simple mechanical element. SOLUTION: The method gives a total gain control value of a differential amplifier, which is as follows; (no load value: 0 dB)+10 log 1+(A or B)} [dB]. The method gives an optimized response characteristic for a control system when an integrating frequency, a differential frequency, and a high-end cut-off frequency are defined as follows; (no load value)×(1/√1+(A or B)) [Hz]. These formulas suggest that the only one parameter can control the gain adjustment. Notes; A = the load mass ratio = (load mass value converted at the motor side)/(movable part mass value of a single linear motor). B = the load moment inertia ratio = (load inertia value converted at the motor shaft)/(rotor inertia value of the motor).
