Power Boiler

The analysis of technological processes for a real control object-a recovery boiler is performed in order to determine faults and possible emergency situations. The recovery boiler is considered as a complex control object (in which a chemical reactor is combined with a steam power boiler), which is advisable to decompose into several interconnected subsystems. The study was carried out in accordance with the HAZOP application manual in the form of a qualitative analysis of faults and possible abnormal situations in the recovery boiler. The study was conducted in accordance with the decomposition of the recovery boiler for each constituent of the interconnected subsystems. As a result of research, for each of the subsystems of the recovery boiler, HAZOP work tables were developed that allow you to identify root frames-linked to specific causes of possible faults.

Onboard Equipment

The complex control system of the helicopter-type aircraft is considered, its design is described depending on the requirements for the aircraft and interaction with the interfaced onboard equipment. The main elements of the system are the subsystems of remote and automatic control of the helicopter. In the process of developing such a system, much attention is paid to ensuring a high level of reliability and maintaining the functions necessary for the safe completion of the flight. Therefore, the main requirement for an integrated management system is the probability of its failure in backup management with improved stability of the control object is not higher than 10-9. The authors of the article conducted the analysis of the integrated management system on accutanecost in conditions of failure of the elements included in its composition. In the course of the analysis the assessment of fault safety of subsystems of remote and automatic control is carried out. At the same time, for each system, the influence of obvious and not obvious failures on the change in the controllability of the aircraft and the safety of its flight was considered. Also, the analysis of the system in the conditions of failure of the on-Board equipment of the device. Special attention is paid to the study of the dynamics of the Executive mechanism of the system in the conditions of failure of the onboard hydraulic power supply system. The paper presents the results of studies of changes in the force, speed and quality factor of the electrohydraulic drive at various failures of hydraulic power lines on Board the aircraft. The obtained results can be used in the process of designing complex control systems, studies of electrohydraulic drives and development of methods for parrying the consequences of failures of the helicopter’s onboard equipment with respect to the complex control system, including the creation of algorithms for reconfiguring the system and the logic of controlling the functioning of its elements.

The Mathematical Model

On the basis of theoretical and practical studies of the electromechanical system, the scientific and technical problem of improving the control system of the electromechanical system during the impact on it of multi-vector perturbations is solved. The result of the study is the integration of differential equations with coefficients dependent on the oscillations of the control object. In the theoretical part, the mathematical model of the electromechanical system was synthesized, which made it possible to investigate ways of minimizing the deviation angles and time intervals required to stabilize the motion of the electromechanical system, which allowed indirectly to realize the associated signal with the stochastic nature of the moment of oscillation of the control object on the coordinate plane. The method of parametric optimization of the mathematical model of the electromechanical system in the function of the angle of inclination is also improved and investigated. Based on the definition of the structure and algorithms of work, the efficiency of the control system of the electromechanical system increases in terms of reducing the stabilization time of the control object.
