Modeling of the Process of Optimization of Decision-Making at Control of Parameters of Energy and Technical Systems on the Example of Remote Earth’s Sensing Tools

Abstract

The authors study the process of decision-making optimization in the control of the spacecraft onboard systems. To ensure the continuous operation of a remotely controlled complex technical system, it is necessary, on the basis of an analysis of the state of the onboard systems, to formulate control effects, the absence of which could lead to the system's failure to fulfill its tasks or system failure. In order to prevent such situations, an approach based on a simulation model is proposed, the use of which will reduce the risk of accidents in the onboard systems of the spacecraft. The proposed model is represented by factor space. The state of the onboard parameters of the spacecraft at different points in time is matched by the set of points that form the decision-making surface in this factor space. The basic stages of forming the optimal trajectory on the decision surface, which are approximated by numerical methods, are given and described. Using the actual values of the parameters obtained in a 15-minute data communication session from the board of the artificial satellite Earth "Ocean-1", a decision-making surface was constructed. The equation of the optimal trajectory on the created surface is obtained. The simulation results will be used to develop emergency management and control systems.

“…From the graph in Fig. 8, the upper and lower limits of the range of oscillations of the fast-oscillating temperature component BOOSK, which is due to anthropogenic factor, and requires the determination of many control vectors ߮ ሬ⃗, providing a set control range for each implementation of the oscillatory process described by equation (1). The final stage of modeling involves multiple implementations of the computational algorithm in MathCAD or Python.…”

“…To solve this problem, we present the environment in the form of a system, which is characterized by fluctuations under the influence of anthropogenic load. In this case, depending on the level of external influence, the system either returns to equilibrium or, as a result of increasing the amplitude of oscillations, is destroyed and not restored, which is equivalent to a catastrophic state [1]. Since the result of general warming is an increase in the average temperature of the planet's atmosphere, it is advisable to choose the climatic parameter is the temperature.…”
