Abstract
This paper describes the problem of automation of choosing the parameters of an electric hydraulic drive controller for a single-channel strength load stand for airframe elements. A parameter configuration method for a proportional-integral stand controller is proposed, based on the results of relay feedback tests and motion separation method. The results obtained make it possible to automatically configure the controller parameters of the strength test stand and improve the accuracy of implementation of force loading cyclograms of structures, which eventually makes it possible to accelerate strength tests. The results of analyzing the implementation of this technique on an experimental stand are given.
