Abstract

The design of the system used for brushless DC (BLDC) motor control
in speed and position control is difficult due to the non-linear structure.
Therefore, the designed controller is required to respond to these challenges
and need high-efficiency operation. This paper presents the experimental
validation of a robust speed control structure of a BLDC motor based on
continuous sliding mode (CSM) and fractional-order sliding mode (FOSM)
controllers. The controllers have been tested for low and medium speed
reference signals and amplitude values. Then, both controllers have been
compared in term of tracking performance and error elimination and the results
have been shown graphically. Experimental results prove that the FOSM controller
shows better trajectory tracking performance than CSM controller with high
precision as well as good robustness against changes of references.
