| Abstract: | After studying the structure model for a beam focus position control system for laser cutting, the performance indexed ought to be met by the system are specified. They are: 1) Regulators that must be in corporated in the controller; 2) The phase angle margin of the system; 3) The cut-off frequency of the system. A PID control scheme is proposed, which will give the system fairly good dynamic and static performances. The control system is tested, and satisfactory slanting and fluctuating objects are achieved. |
