Design of Temperature Control System Algorithm
Abstract: Temperature control is a kind of process control methods which is often applied to industrial production, some of the manufacturing process for temperature control requirements are very harsh, temperature control effect directly affects the quality of products and yield . Most of the traditional temperature controllers are based on 51 single-chip design. While this kind of temperature control systems has low manufacturing cost and convenient operation on hardware, but the temperature control effect is not ideal. Therefore, a new temperature controller is designed based on the STM32F103VE microcontroller in this paper. The main work includes:
1. Hardware design, including CPU selection, temperature sensor selection, button settings;
2. Using C code to write and debug the software program;
3. Two temperature control algorithms will be designed and the effect of temperature control will be compared in the system.
The main difficulty of this design is the application of Characteristic Model algorithm in the temperature control system.
Key Words:STM32F103VE microcontroller; Temperature Control; Characteristic Model
