This paper proposes a kind of design and realization method of real time control system that based on the Windows real time extension module RTX, which can meet the requirement of six-freedom Stewart platform control system to the real time. The design of the control system was divided into real-time layer and non-real-time layer according to the requirements of various functions to the real-time, and the data communication was realized by means of inter-process communication mechanism. The analysis conclusion to experiments data indicates that the control system is stable in operation and good in real-time performance.

Developing a microcontroller-based system for controlling the flywheel motor of high-dynamics spacecraft using Russian-made parts and components made it possible to make statement of the problem of searching control function for a preset rotation rate of the flywheel rotor. This paper discusses one of the possible options for mathematical study of the stated problem, namely, application of structural analysis based on graph theory. Within the framework of the stated problem a graph was constructed for generating the new required rate, while in order to consider the stochastic case option the incidence and adjacency matrices were constructed. The stated problem was solved using a power matrix which transforms a set of contiguous matrices of the graph of admissible solution edge sequences, the real-time control function was found. Based on the results of this work, operational trials were run for the developed control function of the flywheel motor rotor rotation rate, a math model was constructed for the real-time control function, and conclusions were drawn about the feasibility of implementing the results of this study. Key words: Control function, graph, incidence matrix, adjacency matrix, power matrix, microcontroller control of the flywheel motor, highly dynamic spacecraft.
