Based on the influence of the existing problems in the design and application of the fuzzy adaptive PID controller, this paper analyses the current situation of the design and application of the fuzzy adaptive PID controller and the optimization design process, and puts forward the method of how the design technology acts on the system

The main research of this design is taking STM32 MCU as the control core. It collects data through DS18B20 and DHT11 sensors and feeds back to the MCU system through timely detection of temperature and humidity in the space state. It uses the PID algorithm to process the data. The external hardware is directly controlled

It is a basic problem that the control system urgently needs to solve to deal with the sudden change of load, especially the sudden change of large load, to achieve the effective stability of generator terminal voltage value. In this paper, a new intelligent PID controller system is proposed and applied. The PID controller is
