The objective of this paper is to apply the
Hybrid Efficiency Loss Minimization control scheme [1]
into a FOC controlled ACIM motor drive in order to
improve the fast on-line loss minimization control through
flux control,. The proposed controller combines a Loss
Model Controller (LMC) to control the transient states
and a Fuzzy Logic Search Control system (FLSC) to
control steady states. The LMC is based on a simple
generalized model for various motor types with low
accuracy, which provides the real time fast gross
approximation of the optimum motor flux, as a function
of the torque and speed operating conditions, not causing
significant torque ripples. Sequently the FLSC control
system, which consists of two interacting fuzzy controllers,
provides the real-time refinement of the motor’s flux
adjustment on the basis of search during the steady states.
Due to the FLSC the motor’s flux level fluctuates in steps
until the measurement of drive’s power losses settles at a
minimum. The proposed hybrid controller is incorporated
as an outer loop in an indirect flux oriented vector
controlled drive. The model of the suggested controller
designed by using the MATLAB/Fuzzy Logic Toolbox®.
The control scheme is validated by simulation through the
eZdspF2812TM board using Code Composer StudioTM IDE
environment for a FOC AC Induction Motor (ACIM)
drive. In order to validate the importance of the efficiency
optimization during transient states, the same simulations
are done with and without including the computations by
LMC. Experimental results will be available upon
conclusion of the laboratory testing by using the
eZdspF2812TM.
