Abstract：

For the problem of temperature control in integral selfresistive electric heating incremental forming process zone, based on experimental material TC4 titanium alloy and process characteristics of integral selfresistive electric heating incremental forming process, a heating electrode with smaller temperature gradient in incremental forming process zone was designed by finite element simulation. At the same time, based on the principle of fuzzy adaptive PID control, the corresponding fuzzy PID controller was designed, and embedded platform S3C2440 was built. On this platform, the temperature control system of integral selfresistive electric heating incremental forming was developed to accurately control the temperature of the forming zone. Finally, the mathematical model of the temperature control system was identified by step response method, and the scientific nature of the temperature control system was verified by the combination of simulation and experiment.
