Control of a ground mobile robot motion in case of the navigational data corruption of the satellite navigation system64_1.pdf

The article discusses the determination of navigational data corruption, which received by the satellite navigation system as well as traffic control of ground mobile robots.
It also specifies the movement features of ground robots, which affect the data integrity monitoring. It proposes an algorithm of control to implement the methods of autonomous onboard monitoring of the navigational data integrity. The algorithm is based on the equations of signal correspondence in various parts of the control system. It is designed to determine the inoperability of the satellite navigation system that implies the loss of signal and failure in the navigation problem solution. The algorithm takes into account the non-deterministic nature of moving ground robot with possible stops in the process of following the trajectory. The article considers the implementation variants of algorithm to assess reliability for the control system containing additional sensors of the robot’s displacement and for the hardware-redundant system containing no additional sensors. The results of modeling the movement of a ground mobile robot along an arbitrary trajectory in case of navigational data corruption are presented. The features of algorithm based on the simulation results are described in the article.
The authors considered variants of robot control in case of navigational data corruption. The structure of the system and a method for controlling a mobile robot in case of satellite navigation system failures are also proposed. The method is based on the control mode in the system, according to the measured data of the position of the robot in the case of navigational data corruption or otherwise according to the data calculated from the robot model. The implementation of the method makes it possible to avoid significant deviations of the robot from a given trajectory of movement at intervals of signal loss of the satellite navigation system.

Adaptation of displayed flight and navigation data in the aircraft electronic display system61_2.pdf

The problem of flight safety continues to be of great importance in civil aviation, despite today aviation is the safest mode of transport. Particular attention is paid to the human factor, since it has a significant impact on safety. The article analyzes the impact of eye strain caused by displayed flight navigation data on a pilot during landing and discusses how to reduce it. It considers how the pilot interacts with aircraft equipment. The flight data, increasing eye strain, but having no affects on successful landing of the aircraft is specified. The article substantiates the necessity of adaptive display of flight data on the screen during landing. The proposed adaptive method for displaying flight navigation data is supposed to reduce the pilot’s eye strain, which contributes to improved quality of piloting and ensures flight safety.

Architecture Optimization of Functions of Airborne Equipment Complexes on the Basis of Integral Modular Avionics 000_3.pdf

The article deals with the process of designing of an airborne equipment complex based on integrated modular avionics. For a more complete disclosure of the advantages of the new architecture of the complexes, the authors propose to single out the process of designing the architecture of the product functions in the form of a tree in a separate stage. Taking into account that the design process of the complex is closely connected with the process of assessing its security at all stages, the article shows that the design of the product function architecture should be intermediate between technical analysis and safety analysis and the process of circuit design of the product. That allows to perform a primary assessment of the product fault safety level, formulate requirements for the application of methods in order to increase its reliability and fault safety at the early stages of design. Optimization of the architecture of the product functions also allows to justify the hardware requirements of the complex.

Optimization of the Functional Structure of Airborne Hardware Complexes 000_12.pdf

The article shows that it is unnecessary to distribute functions on the basis of their belongings to one of the air vehicle (AV) level in order to take advantages of the integrated modular avionics (IMA) architecture in constructing the airborne hardware complexes (AHC). The method of construction and optimization of the functional structure of AV AHC on the basis of constructing a product functions tree is considered. The basic principles of constructing function groups optimized for implementation on a hardware platform with the desired characteristics are formulated. The authors developed a notion of indirect function realization and described its main advantages and disadvantages. Also, a product functions tree describing algorithm was proposed and outlined. The recursive action algorithm was given by the example of forming one group of functions. The method for improving the load on a hardware unit with its lack of load after the process of forming a group of functions was proposed.

Reliability of Integrated Modular Avionics Reconfigurable Complexes 000_3.pdf

This paper briefly outlines the problems of calculations reliability for multiprocessor systems. The authors show disadvantages of the statistical calculations method for reconfigurable onboard equipment complexes. The preliminary system safety assessment procedure for the system developed is described. The helicopter onboard equipment complex, which is capable to function in cruise flight mode and in modes of landing and takeoff, was considered as an example. Respective hardware and functional graph was built. The graph takes into account functions criticality, data streams between them, and specific hardware features. Operating modes of the complex are also described. Evaluation of developed reconfiguration algorithms effectiveness was implemented with the use of Fault Tree Analysis (FTA) for the traditional federative architecture with double reservation and for the integrated modular avionics architecture that consists of a crate with the reserved commutation module. Respective fault trees were built and the numerical results of reliability evaluation were presented. In order to improve algorithms for performing better reliability, some recommendations are given. The authors also show the impossibility of implementing the reconfigurable architecture on the basis of the existing complexes with the dynamically reconstructive architecture. The architecture doesn't meet the requirements of complexes reliability and doesn’t comply with modern standards for airborne equipment development.
