Simulation design and implementation of thermal control subsystem for satellite simulator

Using Object oriented(OO) method, a thermal control Subsystem for satellite simulator has been designed, which was using to simulate the temperature in the normal and faulty orbit statements. The paper built a complete frame for thermal control subsystem, used a series of mathematic models to describe the temperature sensor, heaters, and adopted the PI and switch control algorithm. At last, the paper accessed the actual ground monitoring and control system with the subsystem to test the functions of the subsystem, which the result shows this design method is feasible.
