| Abstract: | According to the high precise requirement of temperature control,a common EEV control system based on ATMEGA16 MCU and THB6128 stepper motor driver was designed.The temperature gathered by temperature sensor was converted to a digital signal input to the MCU.The running steps of the stepper motor were calculated by the PID algorithm.The opening percentage of the EEV was controlled by driving stepper motor.The high precise temperature control was achieved.The practice shows that the system has higher control precision and lower price. |
