Autonomous Unmanned Aerial Vehicles Control System Intellectualization

Abstract

Among unmanned aerial vehicles (UAVs) control systems the most interest are the systems capable to provide object control the high level of autonomy due to the maximum use of information awareness based on external environment condition and internal UAV status. Firstly, it is the widest range of external influences, in many cases having character of purposeful impact on the ability of the control system to perform its assigned target function. Secondly, it is about the unforeseen internal situations: equipment element failure(s), information security violation, software failure, etc. Functioning process model of such perspective system can be represented by three components: information (provides information awareness with appropriate quality indicators), manager (decides which way to a target to choose) and executive (realizes the action corresponding to the chosen way of target achievement).Such perspective control systems are identified as a class of intellectual control systems with realization of function of information awareness. Сonsider the possible control system structure of an autonomous UAV (AUAV) on the terminal phase of his flight executing a complex of information and administrative tasks with information awareness function implementation while executing main function. The considered system consists of two parts: 1) Ground flight preparation system, making the AUAV flight task (using available and predicted information about external environment); 2) AUAV onboard system, using the current (a posteriori) information about the external environment conditions and a condition of the AUAV, comparison of aprioristic and a posteriori information, making relevant flight management. Basic structural and functional features, such as are inherent in the systems of this class: 1) An aprioristic standard situations set (SSS) preparation and problem subsituations set (PrSS) for each TS; 2) existence of the aprioristic knowledge base (AKB) as the light task (FT) main component; AKB includes base of the allocated interest objects reference descriptions, onboard decision-making algorithms and AUAV flight control for all problem subsituations, processes realization cyclograms of the specified algorithms; 3) Vision system onboard, carrying out algorithms of automatic receiving and processing of a posteriori information, classifying this information to the relevant SSS and PRS / C, priority interest objects automatic recognition, decision-making and AUAV flight control.The perspective control system of AUAV formation technique, realizing an information awareness function is considered on the solution example of interest objects recognition, which are a part of a multi-object stationary land scene; priorities definition and flight trajectory choice.
