Abstract

The invention discloses a multi-motor disc suspension control system and method, and the system comprises: a main control module which is used for the instruction transmission and modeling calculation; a distance measuring module and a angle measuring module which are used for measuring the height and angle of the disc system; a wireless communication module which is used for transmitting measurement data; a motor and a driver which are used for system action; and a coupler and a traction rope which are used for connecting the motor and the disc system. According to the multi-motor disc suspension control method, the system obtains the duty ratio of a motor PWM control signal corresponding to the laser point reaching the expected position through self-adaptive modeling calculation, feedforward control is conducted on actual PID calculation according to the duty ratio, motors in all directions are made to move independently, and the motion synthesis effect is the expected track of the laser point. After the technical scheme is adopted, the multi-motor cooperative control system overcomes the defects of poor environmental adaptability, lower intelligent degree and high time and laborcost caused by the existing table look-up method technology, and improves the reliability, steady-state precision, dynamic performance and intelligent degree of the system.

Description

technical field [0001] The invention relates to the field of electronic control, in particular to a multi-motor disk suspension control system and method. Background technique [0002] With the continuous development of automation technology, the application of a single motor can no longer meet the requirements of highly integrated and intelligent systems. A comprehensive system is often composed of multiple axes and multiple joints. The control of a single motor will affect the accuracy of a certain axis, but when multiple axes are combined together, the effect is not ideal, especially in the high-speed and high-precision field. For multi-motor collaborative control demand is getting stronger. However, the existing high-precision multi-motor cooperative control system mainly uses the precision lead screw to cooperate with the motor to carry the corresponding controlled object, and establishes the numerical relationship table between the attitude of the controlled object an...
