Technology of Two-axis Synchronization Control is very important in industry, especially for the development and manufacture of CNC Machine like SMT machine. Two-axis Synchronization Control is very difficult, some research make it more complex and difficult to realize.In this dissertation, we applied the adaptive fuzzy PID algorithm to the Two-axis Synchronization Control, conducted experiments with the DSP controller and two-axis platform in SMT machine, researched the control algorithm and realize it. The research was supported by the program "modeling and simulating the high-speed high-precision SMT machine and research on the key motion control techniques (NO.SBE201300018)".This paper surveyed and analyzed the theory and application of all kinds of Two-axis Synchronization Control methods at home and abroad, through comparing of some kinds of control methods, we chose the cross-coupled method, using the adaptive fuzzy PID algorithm, researched the control method. We also surveyed all kinds of motion control cards and motion controllers.By comparing the advantages and disadvantages of many controllers, we chose the DSP+FPGA solution, designed the controller with DSP and FPGA chips, analyzed the interference of layout to signal transmission under the high frequency signal, and finally designed the motion controller. This paper used Verilog HDL to design the encoder signal processing unit, in the process we reduced the presence of competing risk in digital circuit. We also Setted up the two ball screw motion control platform, adjusted the mechanical installation position to increase precision, thus setted up the whole motion control system. After that we analyzed the error made in the system, using the laser interferometer test the platform we could get the off-line error module.This dissertation used the soft environment of CCS3.3, programmed in the DSP+FPGA motion controller, and realized parallel control in the SMT motion platform. Also realized the cross-coupled algorithm in the controller, and compared it with the other methods, making sure the algorithm is correct.
