Electric motor driven gyroscope functioning monitor - uses voltage and current measurements on azimuth and elevation motors to obtain function and its integral to derive respective angles

摘要

The process involves determining two functions which contain the current and voltage variable for respective motors providing the azimuth and elevation. These functions are the time derivatives of the azimuth and elevation angles w.r.t. time. The voltage and current variables are measured, and an integrator of each equation is obtained. The integrated functions are combined with their derivative functions according to a prescribed mode of composition. A comparison is then made with information obtained from measuring the respective azimuth and elevation angles in order to obtain a tolerance margin. Control of the azimuth and elevation angles may be effected independently.
