In this theoretical study, interaction capacities between benzene (CH) and MnO clusters, which were modeled with MnO and MnO molecules, were investigated by quantum chemical computations using density functional theory (DFT) with the PBE-D3 functional.

Fault-Tolerant Control Based on Current Space Vectors against Total Sensor Failures.

This paper proposes a fault-tolerant control (FTC) strategy using the current space vectors to diagnose sensor failures and enhance the sustained operation of a field-oriented (FO) controlled induction motor drive (IMD). Three space vectors are established for the sensor fault diagnosis technique, including one converted from the measured currents and the other two calculated from the current estimation technique, respectively, measured and with reference speeds. A mixed mathematical model using three space vectors and their components is proposed to accurately determine the fault condition of each sensor in the motor drive.
