Fedyun R. System of automatic control by multistage draining plants of mines.

Subject of research - multistage draining plants of mines with series connection of pumps - technological schema "the pump in the pump". Goal of research - development the system of automatic control by multistage draining plants of coal mine for increasing the efficiency functioning drainage at the expense of optimization conditions of its operation. The methods of the modern theory automatic control, mathemati-cal statistic, theory of design and treating results the experiments, mathematical simulation, optimum control are applied. Science result: 1) the model of a multistage draining plant with operational mode "the pump in the pump"; 2) the principle of submission multistage drainage in room of state variables; 3) the method of synthesizing a multiply connected system of automatic control by multistage drainage a taking into account designed parametric series of weighting coefficients generalized quadratic yardstick of quality; 4) way implementation the distributed system of automatic control bymultistage drainage and differs from known by unequivocal definition fast-track arguments for a telecommunication network. Practical importance - are designed the method application the simulation of dynamic processes in plants and control systems of the reviewed class, method application of synthe-sizing a digital multiply connected system of control by a drainage, skeleton diagram of a distributed control system by multistage drainage is designed on the basis of network techniques. Sphere of usage is a control systems of technological process of a multistage drainage, control systems of distributed technological plants. The results, obtained in dissertation, are used by institute "Avtomatgormash" in Donetsk, institute "Dongiproshaht", in Donetsk, enterprise "Technological center problems economy energy", in Donetsk.
