Abstract
The problem of designing a control system for a stand for strength tests of aircraft structures is considered. A method for calculating the parameters of a proportional-integral controller (control algorithm) using the motion separation method for the test stand taking into account the delay effect in the control channel is presented. A structure of the adaptive algorithm is proposed that limits the amplitude of high-frequency oscillations in the control system with a change in the direction of motion of the rod of the hydraulic cylinders and provides the specified accuracy and quality of transients at all stages of the loading cyclogram of structures. The results of tests of the developed control system with the adaptive control algorithm on an experimental strength test stand for aircraft structures are given.
