Rozkaryaka P. Development of positional electric drive control system, optimal on thermal losses

Object - the dynamic processes in systems of positional electric drive. Goal - improving energy, static and dynamic properties of the positional electric drive. Research Methods and equipment - methods of optimal control theory, methods of differential and integral calculus, methods of polynomial synthesis, the methods of computational mathematics, mathematical and physical modeling, computer with real time operating system, DAC-ADC board, complete electric drive. Theoretical and practical results - solved an actual scientific and practical problem of increasing energy, static and dynamic performance of systems of positional electric drive by using new methods of synthesis of digital master control devices, implementing optimal thermal losses trajectory, new criteria for setting the regulation loops, the principles of the combined control. The novelty consists in obtaining analytical expressions for calculating the optimal heat loss diagrams for the control of positional electric drive with the restrictions on the electromagnetic motor torque, acceleration, velocity and jerk, and features a digital implementation, subject to the availability of the motor constant magnitude of static torque; to improve the method of structural design of the positional control system, which allows for the desired transfer functions of the system as a whole and its individual units; the further development of methods to assess the static torque of the motor shaft in an uncertain moment of inertia of the system. The degree of implementation - experimental-industrial exploitation on the screwdown structure of mill "1250" Ltd "ArselorMittal Krivoy Rog". Area of use - metallurgy, machine-building.
