Algorithms Of Stable Control Of A Matrix Object In The Conditions Of Parametric Uncertainty, U.F Mamirov
Algorithms Of Stable Control Of A Matrix Object In The Conditions Of Parametric Uncertainty, U.F Mamirov
Chemical Technology, Control and Management
The problems of forming algorithms for stable control of a matrix object under conditions of parametric uncertainty are considered. Algorithms for managing the object under consideration using the matrix pseudoinversion procedure are given. Recurrent algorithms based on the fringing method are used for pseudo-inversion of matrices. These relations allow us to implement recurrent pseudo-inversion of matrices in the control algorithm and, thereby, realize control actions in the adaptive control system of the matrix object under uncertainty conditions.
Steady Synthesis Algorithms Of The Adaptive Observers In Control Systems Dynamic Objects, H.Z Igamberdiyev, A.H Rasulev
Steady Synthesis Algorithms Of The Adaptive Observers In Control Systems Dynamic Objects, H.Z Igamberdiyev, A.H Rasulev
Chemical Technology, Control and Management
The problems of synthesis of adaptive observers are considered, for linear dynamic systems containing parameter identifiers, estimators of the initial and current state vectors. For a stable estimation of object parameters, an iterative process is used, based on the normalized decomposition of the matrix operator of the identification equation. These algorithms allow the stable identification of the parameters of the controlled objects on the basis of the use of regular computational procedures and thereby improve the quality of the functioning of the adaptive observing device.

Increase Of Identification Quality On The Basis Of Genetic Adjustment Of Models Parameters For Description Non-Stationary Objects, A.R Akhatov, N.O Isroilov
Chemical Technology, Control and Management
Paper formulated the problem of increasing the quality of identification for casual time series (CTS), representing non-stationary objects in multicontour control systems on the basis of effective search of global and local extremums when parameters of target optimization function are rational. The new approach is offered to optimization of search by consideration statistical and dynamic characteristics of CTS as specimen of population generation, and by reflection of coordinate points set in space of evolution toward optimal values of target function. The modified genetic algorithm (GA) is developed on the basis of overlapping, generalization of opportunities and use of properties of …

Development Of Algorithm Of Optimum Control Bymultidimen-Sional Discrete Dynamic Objects By Quick Criteria, I.H. Siddikov, M.O. Atajonov
Technical science and innovation
The article deals with the development of a synthesis algorithm in the sense of the optimal control of multidimensional dynamic objects by the criterion of speed. To solve this problem, we propose a modified method based on the representation of a discrete system in the form of a space of state variables and using the theorem on N-intervals. When determining the values of control actions, it is proposed to use the values of predicted errors that allow improving the quality of the control process and will provide high accuracy of calculation of control actions.
