摘要：

针对整体自阻电加热渐进成形加工区的温度控制问题，以TC4钛合金为实验材料并基于整体自阻电加热渐进成形的工艺特点，采用有限元模拟方法设计了使渐进成形加工区温度梯度较小的加热电极。同时，基于模糊自适应PID控制原理，设计了相应的模糊PID控制器，搭建了S3C2440嵌入式平台，并在此平台上开发了整体自阻电加热渐进成形温度控制系统以精确控制成形区的温度。最后，通过阶跃响应法对温控系统的数学模型进行了辨识，并采用仿真与实验验证相结合的方式验证了该温度控制系统的科学性。

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.
