Abstract

This paper describes the problem of automation of parameter selection of an electrohy-draulic drive for a single-channel testbed for the strength load of aviation elements. It is proposed to tune the proportional-integral controller parameters of the testbed on the basis of the results of the tests based on relay feedback and time-scale separation method. The results obtained allow for autotuning the strength testbed controller parameters and increasing the accuracy of the strength load cyclograms, which eventually accelerates the strength tests. The results of applying this method on the experimental testbed are given.
