Method for regulating a test bench arrangement

Abstract

In order to provide a method that improves on the prior art for controlling a test bench arrangement in which a rotating specimen is connected to a rotating loading machine via a mechanical shaft connection and in which at least one angular velocity prevailing in the test bench arrangement is measured, the rotational behavior of the test bench arrangement and thus the dynamic behavior at least of the measured angular velocity and of a specimen angular velocity (ωP) prevailing in the specimen is first of all modeled using a first system of differential equations. Building on this, the specimen torque (TP) generated by the specimen is modeled using a second system of differential equations, a state observer for estimating the specimen angular velocity (ωP) and the specimen torque (TP) is designed on the basis of the first and second system of differential equations, estimates of the specimen angular velocity (ω{circumflex over ( )}_P) and of the specimen torque ({circumflex over (T)}ρ) are determined by means of the state observer, and the determined estimates are used to control at least one control angular velocity prevailing in the test bench arrangement () and/or at least one control torque prevailing in the test bench arrangement.
