Precision Rotary Stand with a Digital Control System and Inertial Sensing Elements

A mathematical model of the operation of a precision rotary stand with a digital control system and two types of gyroscopes is presented. The wave solidstate and optical gyroscopes are inertial sensing elements of the system. The proposed circuit design implements double integration from measuring sensors of different physical nature. The first type of sensors used are optical angular velocity meters, the operation of which is based on the Sagnac effect laser or fiberoptic gyroscopes. The second type of sensor is a wave solid-state gyroscope, the operating principle of which is based on the Brian effect. The third type of sensor is an optical angular encoder a precision measurement of the rotation angle of the test bench platform. The accuracy and dynamic characteristics of the test bench are evaluated; their provision is based on methods for synthesizing digital controllers in the automatic control system of the test bench.
