When the measured temperature is equal to the set temperature, the program returns the temperature setting module, when the measured temperature is not equal to the set temperature, start the PID control module, and then return to measure the display module, so the cycle continues until the measured temperature equal to the set temperature is reached. As the incubator temperature control system with large time delay and nonlinearity, conventional PID control parameters tuning difficult. In this design, a self-tuning PID algorithm, PID tuning to solve the difficult problem. Here self-tuning PID algorithm design process.
