Control System Model

The model of the management system of the mineral resource complex of the region using the feedback principle is developed, the structural composition of the model elements is analyzed from the point of view of the specifics of the management object – the mineral resource complex of the region. According to the control theory, it is necessary to evaluate the effectiveness of the control action by means of a control device as part of the control system model. Regional monitoring of the state of the mineral resource complex of the region and indicators (indicators) of programs for geological exploration of the subsurface and reproduction of mineral resources are used as monitoring devices in the model. The defining influence on the decision-making subsystem comes from the strategy for the development of the geological industry until 2030 and sub-program 1 “Reproduction of the mineral resource base, geological study of the subsurface” of the state program “Reproduction and use of natural resources”. As measuring devices in the control system model, such elements as the calculation of the necessary increase in geological knowledge, the analysis of changes in the balance of security for the forecast period are used. Evaluation of the effectiveness of the system in terms of management theory is implemented by establishing a correspondence between the indicators (indicators) in the state programs and the actual state of the management object at the time of forecasting.

Vector Control System

In the AC control system, vector control theory is very popular as it makes the AC motor achieve the performance as perfect as DC motor [1]. In the paper, the vector control theory is briefly introduced, and then a vector control system model is builded in the matlab/simulink, and the SVPWM technique is adopted. The results show that the improved vector control sytem of PMSM has a excellent performance.

При моделировании системы управления минерально-сырьевым комплексом региона необходимо учитывать влияние рисков на реализуемость горного проекта, как элементов внешней среды. В работе выполнено моделирование системы управления минерально-сырьевым комплексом региона с учетом рисков горных проектов. One of the most important state tasks in the management system of the mineral resource complex, both at the national and regional levels, is to ensure the reproduction of mineral resources. The solution of this problem can be modeled using the theory of control of active systems, which, of course, can be attributed to the mineral resource complex. When modeling the management system of the mineral resource complex of the region, it is necessary to take into account the impact of risks on the feasibility of a mining project, as elements of the external environment. In this paper, the authors have modeled the management system of the mineral resource complex of the region, taking into account the risks of mining projects.

The article presents the analysis of the automatic control of the bioethanol production process intended for biofuel. It presents the formulated general concept of the system and the method of designing a closed control system based on the iterative prototyping procedure. The modeling and the simulation were carried out in the Matlab®-Simulink environment. The simulation model of the object was developed based on the experimentally registered characteristics. It has been adjusted, i.e. the compatibility of its behavior with the object it reproduces has been confirmed. Based on the tuned model of the object, a control system model was created, which was the basis for computer simulation which enabled the control algorithm parameters to be established. The final verification of the correct operation of the system was performed with the use of hardware simulation. It was based on entering a negative feedback loop of the virtual control system of the real object elements into the loop. The results of the simulation confirmed the correctness of the adopted design.
