This paper using digital signal processor TMS320VC5402, which adopted PID algorithm, through modify duty cycle of the output pulse, which means to realize PWM electrothermal furnace temperature control. Temperature feedback signals through sampling, the AD PID algorithm, and set the initial value, control the XF output pulse width. Test results show that the system has a short transition time, small overshoot and stability characteristic of low error.The design for temperature control of the implementation, application requirements and improve system control, precision, speed, power consumption has some practical significance.Key words: PID, DSP, TMS320VC5402, temperature control下载后可任意编辑目 录摘 要..........................................................................................................................................................I1 绪论.........................................................................................................................................................11.1 本课题讨论意义........................................................................................................................11.2 ...
