【Abstract】 This paper introduces a digital PID embedded temperature-controlling system. The system consists of the PC104, sensor circuit, the change-send circuit, the cntrollable silicon circuit, the functional package of the PID software and the functional package of the non-linear emendation software, possessing the function of real-time control and automatic temperature modulation. This paper focuses on the software-design of the system,which achieves the PID arithmetic and the non-linear emendation on the sensor with VB.更多还原
