| Summary: | Various control algorithms have been investigated for speed sensorless of an AC motors
using three-leg inverter by other researchers. Unfortunately, these sensorless techniques are mainly
focus on single motor controlled drive with a single three-le inverter. Resent research has shown that
the dual-motor drives can be independently controlled by using a Five-Leg Inverter (FLI). This paper
introduces the new control strategy based on speed sensorless technique of independent dual-
Permanent Magnet Synchronous Motor (PMSM) drives using FLI. The simulation is implemented in
MATLAB/Simulink to evaluate the overall motor drive performance. The transient behavior is
examined for various speed commands, load disturbance, inertia and during zero speed operation, so
that a thorough comparison is enable. The simulation results also proved that the performance
characteristics of sensorless dual-PMSM are almost similar to the sensory system except for the startup
condition. For future research, there is a need to emphasize on the start-up method for sensorless
dual-PMSM drives. |
