The Fault-Tolerant Control of Induction Motors
To eliminate the negative consequences of the operation of an electric drive with defects and damage to induction motors, the monograph presents methods and systems of fault-tolerant control that allow the adjustment of the operating modes using the means of a variable-frequency electric drive. The main idea of such systems is to maintain the operability of technological mechanisms in the event of various malfunctions. The worked-out methods and systems make it possible to detect various types of damage at the initial stages of their development. Then, based on the obtained information, they allow upgrading the control algorithm to maintain the electromechanical equipment’s operability to replace the related equipment or repair the electric drive motor. The most rational area for using the developed fault-tolerant control systems is industrial equipment, which must continue operating despite the deterioration in dynamic characteristics and energy efficiency.
