Abstract
The tiny machine control of go against and change the transistor welding power supply, at raising the function and the welding quantities of weld the power supplies, and push forward the application of weld the robot, all having the obvious value.Should open the following research work of exhibition for this:(1)Excellent turn the structure parameter of the welding power supply of the tiny machine control, become the series turn combine in actually produce the expansion is applied.(2)The control calculate way that lead into the forerunner, such as from correct the PID, from organize the nerve network of the misty control and mature control technique, raise to control the accuracy.(3)Adopt the hungry design method of soft hardware that the function mold piece turn, strengthen the kit research that the tiny machine controls the system, the easy to batch quantity turns the production.The development of the micro-electronics technique, the calculator technique and the artificial intelligence control theories, will make the function of weld the power supply leap onto a new step.
This text mainly includes the four-part cent.The first part was detailed to introduce the basic request and principles of the welding power supply, including its classification and characteristicses;The second part then to should design to do the project argument and overall design, give the origin designs a system with minimum machine, the confidence that had to this design a macro view;The third part designs for the hardware, detailed introduced and should design each machine piece need and go against to change the power supply of from examine a patient the function, the machine piece use mainly includes:8031,74 LS373s, EPROM2764, ADC0809, DAC0832, the electric current huor spreads the feeling machine and CW3524s.The four-part cent then designs for the software, introducing the control calculate way that should design to use:The PID control calculate way.
