Problems solved by technology

[0002] The miniaturization and integration of electronic components requires higher processing accuracy for high-speed and high-precision electronic manufacturing equipment. However, the vibration generated by the elastically deformed conveyor belt restricts the processing accuracy of the equipment.
In the study of conveyor belt vibration control, the conveyor belt model has the characteristics of strong coupling, infinite dimension, and large acceleration and deceleration motion. Modeling high-frequency modes may cause spillover effects and affect the stability of the system.
In recent years, there are methods to combine some control methods, but the considerations are not complete, and most of them are still at the level of theoretical analysis, and can only roughly compare the vibration data before and after the control input

Abstract

The invention discloses a large acceleration and deceleration conveying belt vibration PD control system with unknown disturbance. The large acceleration and deceleration conveying belt vibration PD control system comprises a conveying belt model analysis display module, a serial port communication module and a control module. The three modules are classified according to functions and are not absolutely independent on the aspect of programming. The conveying belt model analysis display module mainly utilizes a difference discrete method, is achieved through MATLAB GUI programming, and is displayed on a PC. The serial port communication module is embedded inside the conveying belt model analysis display module and the control module, and data communication between the conveying belt model analysis display module and the control module is guaranteed through the serial port communication module. The control module is located on an ARM development board and conducts data monitoring and control actions on a vertical tube model by utilizing an Android system. The large acceleration and deceleration conveying belt vibration PD control system with unknown disturbance achieves real-time dynamic displaying of vibration of a conveying belt and effect displaying after a control algorithm works, and is low in cost and more convenient to use.
