N2 - Fiber Optic Gyro (FOG) is the core component of the FOG-Based Strap-down Inertial Navigation System (SINS). Since FOG is sensitive to the temperature changes, it is necessary to establish a temperature control system to guarantee the FOG-Based SINS in the proper temperature (20-30 degrees) while the ambient temperature changes. On the basis of a 2-level temperature control system developed in our previous work[3], a thermal control system with Thermoelectric Semiconductors Cooling (TEC) is established in this paper. Our contribution consists of three parts. Firstly, a thermal dynamics model of FOG-based SINS, which TECs are installed stick on the shell of FOGs, is established via computational fluid dynamic (CFD) simulation. Secondly, the thermal control system with reduced-order modeling (ROM) is proposed through Proper Orthogonal Decomposition (POD) and prediction error method (PEM). Thirdly, a thermal control system using Linear Quadratic Regulator (LQR) is established in Simulink platform. The results of CFD simulation show that with the thermal control system, the temperature of the FOG in SINS can be controlled in the proper temperature while the ambient temperature changes.
