Precision Temperature Control for the Laser Gyro Inertial Navigation System in Long-Endurance Marine Navigation

Abstract: In the Ring Laser Gyro Inertial Navigation System (RLG INS), the temperature characteristics of the accelerometer can directly influence the measurement results. In order to improve navigation accuracy in long-endurance marine navigation, the operating temperature of the accelerometer should be precisely controlled. Based on thermal studies on the accelerometer, temperature control precision should be better than 0.01 °C to achieve 1 × 10−5 m/s2 output accuracy of the accelerometer. However, this conclusion is… Show more

“…5 Generally, the problem of large inertial constant, time delays, and multiple disturbances are the main challenges faced by temperature control system. The combination of control algorithms, such as fuzzy control, 6,7 genetic algorithm, 8 neural network control, 9,10 feedforward control, 11,12 and Smith predictor 13 with PID control algorithms, is a common used approach at present. Moreover, the integration of intelligent control strategies, such as fuzzy algorithms 14 and iterative learning control, 15 with advanced techniques like predictive control, holds significant promise in addressing challenges encountered in industrial control systems like time delays 16 and external disturbances.…”
