Precision control of high speed conveying mechanism based on CAN bus communication

The study describes demands for conveying mechanism in the development trend of the manufacturing sector and clarifies the significance of research for conveying with high speed and stability. Several motion control algorithms were analyzed as a mathematical model of motion control. At the same time, to accomplish the same displacement, the specific formula functions were solved with the boundary conditions and each function was simulated and analyzed using MATLAB software. Then according to the displacement-time, velocity-time and acceleration-time theoretical curves, the characteristics and effects of each motion algorithm were obtained. Afterwards, the research object, roller screw conveying mechanism based on the Cartesian coordinate system, was introduced including the motion control system based on CAN bus communication and the signal detection system using a laser interferometer. Followed by collections and analysis of the experimental data, the displacement-time, velocity-time and acceleration-time experimental curves were obtained with the characteristics of different algorithms. Lastly, combined with motion effects of different algorithms, a best algorithm was obtained, which is the most stable and gentle with less vibration.
