Abstract. The problem of control of a linear plant, which mathematical model is described by the singular- disturbed differential equations with an a priori unknown parameters, is solved. The algorithms of control providing indemnification of parametrical and external disturbance with required accuracy, as well as conditions under which the initial model may be decomposed by allocating of fast and slow components, are received. The received results are illustrated by a numerical example.

Keywords: robust control, observer of the derivatives, singular- disturbed system, state vector, auxiliary contour.

Abstract. The method of solving control problem for nonlinear dynamic systems with faults on the basis of logic-dynamic approach is suggested.

Keywords: nonlinear dynamic system, fault, fault-tolerant control, logic-dynamic approach.

Abstract. General principles, approaches, methods of investigation have been formulated and control actions directed to provision of technogenic safety have been determined. Considered are accidents and technogenic extreme situations, which are conditioned by destruction or depressurization of unique mechanical systems inside technological complexes exploited for the processes running under extreme values of technological parameters of hazardous agents. Some issues related to investigation and control of the states of technological complexes and unique mechanical systems inside them are discussed.

Keywords: technogenic safety, cause-effect complex, states, technique, models, knowledge, experience, information technologies.

Abstract. The article investigates a problem of data validation in control systems. A so-called syncromodel is suggested as a solution. It is based on simulation of control object and interval calculations. Syncromodel functions synchronously with the control object. Fuzzy sets theory is used to determine the measure of data validity.

Keywords: data validation, cleaning data, synchromodel, dirty data, control systems, parameters, simulating model, fuzzy set.

Abstract. The problem of planning of programmed control of mobile object under conditions of deficiency and aprioristic uncertainty of time allocated for the planning is considered. For solution of this problem algorithms for fast estimation of vectors of parameters of high dimension are suggested.

Keywords: vector of indignations of high dimension, algorithm for fast estimation, deficiency of time estimation.
