Abstract

The invention relates to a method for achieving follow-up control of a laser cutting head based on linear state error combination. The method includes the following steps of: carrying out human-computer interaction through an NC Studio platform, finishing related parameter setting and executing a start-stop action; calculating a linear deviation related code through an EX33A control circuit; issuing a corresponding control instruction to the EX33A control circuit through a motion control card; carrying out linear combination on the position and speed deviation estimated by a composite trackingand state observer according to the distance plate information received by a capacitance amplifier by using the EX33A control circuit; amplifying the control instruction through a driver. The invention further relates to a system for achieving follow-up control of the laser cutting head based on the linear state error combination. By adopting the method and system for achieving follow-up controlof the laser cutting head based on the linear state error combination, the linear combination of the state deviation is applied to a laser head follow-up control system; and the operation complexity of a control algorithm can be reduced and the operation efficiency is improved on the premise of guaranteeing the control effect.

Description

technical field [0001] The invention relates to the field of laser cutting follow-up control, in particular to the field of control law design, in particular to a method and system for realizing the follow-up control of a laser cutting head based on a combination of linear state errors. Background technique [0002] ADRC algorithm is mainly composed of tracking differentiator, extended state observer and nonlinear combination. In the active disturbance rejection control algorithm, the nonlinear feedback specifically refers to the nonlinear combination of the estimated output of the extended state observer and the expected output of the differential tracker according to the actual situation of the system. The nonlinear control law is used in the existing algorithm, which leads to complicated debugging of control parameters. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a...
