The authors have developed mathematical models for researching the electromechanical processes of switched reluctance starter-generators of vehicles, asynchronous electric drives of a crane-manipulator of a radioactive metal decontamination installation, an above resonance vibration machine with two-shaft unbalance vibration exciters for concrete mixtures compacting.
The influence of the parameters of switched reluctance starter-generator, battery and control algorithms on energy efficiency and the nature of electromechanical processes in the starter and generator modes has been scientifically substantiated.
The method of electric drive control by position of the crane-manipulator load-lifting device has been improved, which increases the crane load positioning speed and accuracy and consists in the synthesis of a position control system with a device for setting the angular position steady value, a proportional-integral speed controller and a linear proportional position controller.
The efficiency of using a scalar law control of an above resonance vibration machine electric drive with a supply voltage stepwise increase when approaching the resonant zone during the starting process has been proved, which ensures that the motor torque exceeds the vibrational torque and avoids the drive motor “jamming”.
Received further development the methods for predicting the reliability of induction motors and its bearing units based on the analysis of vibration processes parameters and changes in stator winding temperature and the methods for experimentally determining the operational reliability of induction motors, taking into account operating conditions and changes in the state of the main structural units.
