The Design of Temperature Control System of Test Chamber Based on Predictive Control Algorithm

摘要

In many areas of scientific research and production practice, the temperature is an important physical quantity need to measure and control. It is closely related to almost all of the physical and chemical processes and has great influence on the industrial production process and quality. Put the test chamber temperature control as the breakthrough point to research the predictive control theory and set up the predictive control algorithm model, to design and construct the test chamber of temperature measurement and control system. The system adopts the platinum resistance temperature sensor to test the temperature in the test chamber for real-time measurement. When the data is processed by the single-chip computer, it heat the control circuit accord the predictive control model to realize the accurate control of temperature. The system can set the preset temperature through the keyboard on the instrument panel, and the displayer can display the temperature for real time in the test chamber.
