Abstract


These years, as the development of the science and technology, the application ofwelding technology becomes wider and wider. Among these welding technologies, inverterwelding power source has many advantages such as smaller in size, lighter in weight, higherin efficiency, better electrical properties, easier to apply intelligent control and so forth. As aresult, such power source will be the main development direction.The topic of this thesis is the constant current control of TIG welding machine.Currently, the inverter type of power source in the TIG welding machine controller adoptsthe hard-switching circuit, such power device will generate high power dissipation and thedissipation will increase as the increase of frequency. Soft-switching technology wasadopted to solve the dissipation problem. This thesis adopted the PS-FB-ZVZCS-PWM typeof soft-switching Circuit topology structure. At the same time, in order to avoid thedisadvantages of traditional PID control scheme, particle swarm neutral network algorithmis adopted to optimize the PID control scheme. Simulation of the algorithm was built inMATLAB2010a/Simulink. With the help of the smart particle swarm neutral networkalgorithm, the output of the system becomes closer to the expected value and the constantcurrent control of the TIG welding machine controller was achieved. According to thesimulation results, the PID control algorithm of the particle swarm neutral network has greatvalue and meaning to the constant current control of TIG welding machine.Based on the simulation results, the software and hardware design of the constantcurrent control of TIG welding machine was completed, the TIG welding machine controlsystem was also created. Hardware includes the main circuit, sampling circuit, IGBTinverter circuit, keyboard and display circuit. The software is the C code based on CCS3.3,including main program and interrupt routine. Finally, constant current control of TIGwelding machine was achieved. According to the results, the software and hardware controlschemes can fulfill the requirement of TIG welding machine constant current control.
