Abstract

The article discusses the problem of optimization of complex technical system (CTS) tests under conditions of dynamic loading while maintaining the required accuracy of determining the parameters of this CTS. A model for selecting CTS performance specifications is constructed in accordance with the specified reliability of these systems, based on the use of direct methods of optimal control under conditions of dynamic loading at the development stage. For a stable solution of this problem, a direct modified gradient method of accelerated descent is proposed, which combines the method of steepest descent using the accelerated search method.
This method, unlike the existing gradient methods, allows to significantly reduce the number of ground CTS tests and their cost by using the accelerated search method, while maintaining the required accuracy of CTS parameter determination. In addition, by introducing regularization parameters, the stability of the solution of this problem increases. 

Key words

reliability of complex technical systems; optimal control methods; ground tests; cost reduction; mathematical models of a sustainable solution
