Efficiency and quality of operation of local automatic control systems as part of an autonomous object is mainly determined by the regulator in their composition and the used control law, for the synthesis of which is necessary to use modern computer-aided design systems. The article presents the results of the application of genetic algorithm as a method of parametric synthesis of the PID-controller implemented in the SimInTech visual dynamic modeling environment, which currently is used by enterprises in the rocket and space sectors of Russian Federation. Object of research is the dynamic negative feedback system on the example of the automatic angular position of artificial satellite control system. The functional scheme and the simplified mathematical model of the system in the form of the transfer functions of its links are presented. The computer model of the system as well as a process of synthesis of the controller are implemented as a package of projects, based on standard blocks and submodels SimInTech. Projects interact using a common signal base, which provides information exchange between projects, making the system model flexible and versatile. An interactive computing environment for programming language Python, Jupyter Notebook, is used as a third-party software. The organization of interaction between SimInTech and Jupyter Notebook is described, scripts of programs for its implementation are presented.

The energy efficiency of solar panels is largely determined by the accuracy of their orientation to the Sun. The article presents the results of the development of a software control system for the orientation of the solar panel, depending on the geographical location and calendar date. The system model is implemented in the environment of dynamic modeling of SimInTech technical systems and includes a model of a complex of electromechanical devices for solar panel orientation, a discrete PID controller and a software control unit, which are implemented on the basis of standard SimInTech blocks and submodels. The panel orientation system allows to change the coordinates of the azimuth and location that determine the orientation of the panel in three-dimensional space and control them according to a given program. The system is implemented as a package of projects that interact through a common signal base, which provides information exchange between projects, making the system model flexible and universal. The result of the control system is presented in the 3D module of the visual editor, which allows you to visually track the results of management and the efficiency of equipment use. To confirm the quality indicators of the orientation control of the solar panel the percentage of the received energy capacity is calculated.
