Abstract A simulation problem for echo signals of two-position radar systems is considered. A four-point configuration of the two-dimensional geometric model is proposed to solve it. Relations are obtained for the arrangement of radiators of the model provided that the signals at both reception points are cophased. Based on these relations, we design an iteration algorithm to form the matrix of radiators

An improved formulation of the problem of decision-making

Abstract The features of controlling the movement of a walking robot with orthogonal propulsion when overcoming obstacles are considered. The problem of the coordinated control of horizontal and vertical displacement drives is formulated to implement a motion mode that ensures optimality in the given criterion. The criterion of optimality is the minimum heat loss in the drive motors. A methodology

It is assumed that a corresponding dynamic system has a variable parameter that describes the control-impact gain factor. An iterative numerical–analytical method designed to form autorotation modes with assigned

An algorithm for designing an optimal robust control system with a given value of this limit is presented. The effectiveness of the algorithm is demonstrated by numerical examples.

Abstract A number of fundamental decisions that will determine the technical and economic characteristics of the project in the future are laid when creating new products at the image design stage. Therefore, it is very important, on the one hand, to form and, on the other, to evaluate a large number of alternatives that cover a wide space of possible engineering solutions. Alternatives are evaluated

Abstract A variant of the synthesis method for controlling a linear MIMO system by an output vector is developed that provides the given spectrum of a multidimensional dynamic system in the state space. It is based on the principle of duality of the task of controlling a MIMO system by a state vector and the task of constructing a state observer. The algorithm, without any changes, is applicable for

A mathematical model of the robot is constructed and its equilibrium conditions on an arbitrarily oriented plane are investigated. In order to optimize the energy consumption, an algorithm of the adaptive control of an aerodynamic pump is proposed

Abstract A method for identifying models of a given specification based on the use of the maximum admissible estimates of the requisite parameters is presented. This method provides parametric identification of models in the case when prior information about the system under study is characterized by a small number of observations and its uncertain character cannot be neglected. The method is validated

This algorithm forms the return trajectory to the reentry point of the atmosphere satisfying the given constraints, taking into account the current ephemeris and the fact that the gravitational fields of the Moon and

A general technique for managing the redundancy of the complex at the design stage is formulated in the case of ensuring the invariance of the given set of transfer functions. A formalism is obtained for solving the integration problem of a complex when it is configured as a

Abstract The capabilities of using single-gimbal control moment gyroscopes (CMGs) for the attitude control of Earth remote sensing (ERS) satellites are studied. The situation of the incomplete spinning of CMGs used for controlling the angular motion of the satellite when these gyros have a different angular momentum is considered. Control algorithms that can be applied in this situation are proposed

The switching times and the number of

This method can be used to simply determine the parameters of periodic motions and their stability in the class of systems

An algorithm for detecting and classifying such anomalies is proposed and is tested on the data from the archive of the video monitoring of volcanoes on Kamchatka. The results obtained suggest the possible use of the developed

To obtain real-time estimates using a low-performance computer, a new discrete finite-dimensional filter

Abstract A class of linear periodic impulsive systems with a delay is considered. Sufficient conditions of asymptotic stability are established for systems of this class, reducing the study of the original system’s stability to a similar problem for a system of linear impulsive differential equations (without a delay). This auxiliary result is used to study the interval stability of a linear impulsive

The periodic modes of the system’s movement, in which the hull’s speed is also a time periodic function, are studied. The questions of the existence and uniqueness of periodic modes of system

Abstract The model of (AC’s) movement in the takeoff phase is based on a predetermined scenario for this phase containing many parameters that uniquely determine the trajectory. The rational values of these parameters are selected according to the criterion for the specific safety conditions. The equations of motion of the center of mass in the vertical plane are used as the AC’s motion model with
