The work is devoted to the synthesis of logical control by a robotic arm when unsteady obstacles appear in the working area. For a two-link manipulator, a grip motion control model based on a hybrid automata with a finite set of states is constructed. Using the methods of numerical simulation, the operation efficiency of the obtained logical control algorithm is illustrated.

A representation of the microfinance process in the classical algorithmic sequence is proposed. The basic stages that affect the process itself and the goals of microfinance are highlighted. The case when it becomes necessary to solve the problems of enumeration of possibilities is highlighted. The relations of dynamics on the basis of which the legislative standards of microfinance organization activities are predicted are given.

The procedure of dynamic feedback synthesis was developed, which provides tracking of a given trajectory by the center of mass of an unmanned aircraft. Under conditions of incomplete information on state variables and derivatives of the driving actions, invariance is ensured with a given accuracy with respect to external uncontrolled disturbances. The main result of the work is the synthesis procedure of the differentiator of the given actions, built on the basis of a virtual dynamic model with an unknown input.

The problem of compensating for external disturbances is one of the oldest problems in the classical theory of control. The article considers the task of stabilizing the output variable under the influence of external non-smooth disturbances, that do not belong to the control space. A discontinuous control law has been developed to provide a prescribed control accuracy for the output. Various variants of the transient process in the closed loop system are described, estimates of overshooting and steady-state error are given. The proposed approach can be widely used to compensate the bounded external disturbances, including those, that depend on the state of the system.

This paper presents the results of primary data processing of the experiment carried out at the Institute of Control Sciences to study the aging of the U5 KV400 electric motor, developed by the T-motor company for use in copters. As the engine deteriorates, an increase in the amplitude of the vibration and sound signals is observed and the frequencies at which this occurs are determined. In particular, it is expected that an increase in the amplitude of vibrations and sound at the magnetostriction frequency can serve as an informative sign of the increased engine wear.
