Dudnyk A. Optimal control system transients power saving objects with variable parameters

Object of study: transients in automatic control systems power saving objects with variable parameters. The purpose of the study: the development of an optimal control system of transients in power saving objects with variable parameters and a restriction on the coordinates controlled by adjusting the current charts. Research methods: fundamental principles of the theory of optimal control is used to select the optimality criterion and study the conditions of special controls existence. Numerical methods for solving differential equations used to solve the problem of finding optimal control and define the boundaries of the optimal control algorithms existence. The theory of electric machines was used when constructing mathematical models of positional electric drive. Methods of the theory of artificial neural networks and theory of identification used to develop models drive based on recurrent neural networks capable of identifying parameters. Theoretical and practical results: the developed model in the form of a recurrent neural network of Elman, and the deduced mathematical relationship between weight coefficients and the object parameters. A 6 algorithms of optimal control for a quadratic criterion were obtained. The region of solutions existence was determined. The synthesis of two-level control system was performed. Novelty: is that was first proposed calculation of the contact points of algorithms for the optimal control and rapid method of finding the optimal algorithm with the power space using. Level of implementation: the results were applied in the development of control system training sets of the tank BM "Oplot" and BTR-4 on SE "KMDB" (Kharkiv) for the identification parameters of the actuator and optimal control to the module guidance and stabilization armament. The main provisions of the dissertation are used in educational process at the department of automatics and control in technical systems of NTU "KHPI" when reading the courses " Theory of automatic control", "Modern problems and methods of mathematical and computer modeling" and diploma design. Scope: scientific results of the work can be used by businesses who are developing new and upgrading existing control systems of positional electric drive, which is the main part of working time is in the starts/stops mode and reversing.
