Application of the Maximum Likelihood Method When Combining Information from Primary Meters in a Precision Rotary Test Bench with Inertial Sensors and a Digital Control System to Improve Its Accuracy

The paper examines the operation of a precision rotary test bench with an excessive number of primary meters, some of which are used as inertial sensitive elements in the digital control system of the test bench. Application of the maximum likelihood method for combining the information from the meters, which improves the accuracy characteristics of the rotary test bench, is shown. A method for obtaining the integral estimation of the angular rate of the test bench platform is presented.
