Abstract:
RING LASER GYRO (RLG) is a sensor to sense angular information very precisely. It uses the principle of sagnac effect. In order to get excellent performance from a ring laser gyro, Intensity of laser beams, path length of the cavity and also the dithering mechanism needs to be ultra stable and maintained consistently. Hence control algorithms and hardware is implemented in RLGs for these three controls. Most of the algorithms implemented are linear algorithms and simple in nature. It is felt to use non linear algorithms based on the dynamics of the RLG to improve the performance of an RLG.
So in this project it is proposed to study the principles involved in an RLG control and simulate the dynamics for understanding the non-linearities and finally design new control algorithms for controlling RLG. MATLAB/ LABVIEW is proposed to be used for realizing these algorithms and finally implement them in DSP.
