Motor synchronous control technology has been widely used in lifting device. The effect of Synchronous control technology to improve the precision is becoming more and more attention both at home and abroad. Based on the four channels winding ascension, we design a deviation coupling based on principle of displacement compensation control system, and use Matlab/Simulink for simulation, and research the influence law of different parameters on synchronization control accuracy. The simulation results confirmed that the strategy can satisfy the control precision. Finally, we set up the experimental system to verify the feasibility and practicability of the synchronous control system.

The second module is presented to implement three-axis current vector controllers by hardware, and VHDL (VHSIC Hardware Description Language) is applied to describe the controller behavior. Therefore, a fully digital motion controller for wafer-handling robot, such as three current vector controllers, three position/speed controller and one trajectory planning are all can implemented by a single FPGA chip. Finally, an experimental system constructed by an FPGA experimental board, one three-DOF wafer-handling robot, and three inverters is set up to demonstrate the correctness and effectiveness of the proposed SoPC-based motion control system of wafer-handling robot.
