Angular Movement Control of Single-Axis Test Desk of Gyro-Systems

Abstract

The paper presents design issues of a single-axis stand for testing of gyro devices and systems. Required accuracy of angular velocity is implemented using the inertial sensors (accelerometers) in the system of work platform control of the test stand. Mathematical model is developed for selected kinematic scheme. Block diagram of control object is determined. Design of the single-axis test stand on basis of BLDC motor is proposed. Main structural components of developed design are described. Compensating device (regulator) is selected on basis of analyzing of the algorithms of angular movement automatic control. Method of regulator adjustment in optimization mode of VisSim is investigated. Ability of obtaining of required transient process characteristics by means of PI controller is justified. Modeling of a system with synthesized regulator is carried out. It is noted the possibility to apply the results for determining the regulator parameters of separate channels of biaxial and triaxial test desks.
