*Kravchenko O.A., Barylnik D.V., Sukhenko N.A.*Measures providing safe operation of mechatronic system training complexes (0004-0009.pdf)

When constructing various mechatronic systems, special attention needs to be paid to the issues related to the training system’s safety. The article provides a comprehensive set of engineering controls which allow ensuring the safety requirements for weight compensation stands of the training system.

A sound engineering solution is given to enable a dynamic slowdown condition with the synchronous permanent magnet motor coupled with frequency converter during a long power dump. In order to set the modes of speed and position limitations in force controlling systems, it is proposed to put in speed and position feedbacks as soon as the coordinate values of the electric drive are exceeded. Engineering solutions that ensure compliance with electrical safety norms are studied.

The research group presented the oscillograms of the electric drive performance with an active load torque in the dynamic slowdown mode and in the speed and position limitations mode from Vyhkod 2 ("Exit into Space") training system operated at Yu.A. Gagarin Research Cosmonauts Training Centre (Federal State Budget Institution).

*Usinin Yu.S., Grigorev M.A., Sidorenko N.Yu.*Power circuits of reluctance synchronous electric drives with independent control by excitation channel (0013-0016.pdf)

The article presents the main-circuit schemes of field regulated reluctance electric drives. It is shown that the number of switches is defined by the number of phases and lies in a range from 2m to 4m. Using regression analysis method it was found that the semiconductor converter unit price for small current values does not depend on the current value and is determined by the microprocessor control system price. At currents greater than 100 A the relationship between the price and the current is nearly linear, so replacement of a three-phase semiconductor converters power circuits configuration with a polyphase configuration does not increase the weight or size of the power source. Thus, the complication of power circuits configurations (increasing the number of phases) for technological installations with rated capacity of more than 200 kW allows to improve the weight-size parameters of the electromechanical converter without increasing the size of the semiconductor converter.
