Abstract

The problem of testing the quality of control algorithms for an astronaut saver, i.e., a device for rescue of astronauts (DRA), is considered. The suggested testing simulator is based on a dynamic stand (CF-18 centrifuge). This stand enables simulation of conditions for astronaut sensory conflict of weightlessness. An appropriate algorithm of weightlessness simulation, used at the Cosmonaut Training Center (Russia), subjected to the expertise of many astronauts and would-be astronauts is described. Testing the accuracy of DRA control implements a procedure of maximin testing. The worst parameters of DRA obtained as a solution to the maximin problem are used at the second stage of testing, as inputs for a program simulating DRA motion and visual environment near an orbital station.
