Temperature Control and Simulation of TemperatureAltitude Test System

The temperatureAltitude Test System (TATS) supplies various testing environments. The traditional PID method controls the temperature in TATS TemperaturePressure Cabin (TPC) over a long adjusting time and with a large overshoot. In order to solve this problem simply, a temperature control strategy with temperature difference corresponding factors is presented through a dynamic analysis and modeling of TPC temperature change. The TPC temperature descending process is simulated, and the results show that this control strategy can allot the proportion of PID heating controller and PID cooling controller in the whole control process and TPC temperature can be controlled at a set point quickly and effectively.
