Multiple closed-loop feedback control system of laser cutting machine

The utility model relates to a multiple closed-loop feedback control system of a laser cutting machine, and belongs to the field of computer numerical control application. The multiple closed-loop feedback control system includes a position order controller, an X axis raster ruler encoder, a Y axis raster ruler encoder, an X axis raster ruler, a Y axis raster ruler, a position signal adder, a position controller, a speed signal adder, a Y axis servo motor encoder, an X axis servo motor encoder, an X axis servo driver, a Y axis servo driver, a current signal adder, a Hall current monitoring sensor, a current controller, an X axis servo motor, and the like. The above devices form a multiple closed-loop feedback system, like a current loop-speed loop-position loop feedback control system, a current loop-speed loop feedback control system, a speed loop-position loop feedback control system or a current loop-position loop feedback control system. The multiple closed-loop feedback control system of the laser cutting machine can enhance the stability, the rapidity and the accuracy of the servo motor, and can also improve the output characteristic of an open loop control system, a semi-closed loop control system, and a single closed loop control system.
