Development of a Servo Control System With Parametric Adaptation for Rotary Test Stands

A solution to the problem of parametric adaptation of the servo control system of a rotary test stand to the current moment of inertia of the payload (test object) is proposed. The determination of the current moment of inertia of the payload is based on the implementation of feedback from the current sensor of the servo motor windings when reproducing motion with constant angular acceleration. The dynamic change in the moments of inertia of the payload is compensated by adaptive reconfiguration algorithms of this system, which leads to the preservation and maintenance of the set motion control quality parameters. The paper investigates the frequency characteristics of the control circuit for the rotation speed of the faceplate of a rotary test bench at various values of the moments of inertia of the payload mounted on the faceplate of the stand in order to determine the dependence of the contour characteristics on the value of the current moment of inertia of the payload.
