- Abstract
- In this paper, a robust adaptive backstepping control is
developed for efficiency optimization of induction motors with
uncertainties. The proposed control scheme consists of efficiency flux
control(EFC) using a sliding mode adaptive flux observer and robust
speed control(RSC) using a function approximation for mechanical
uncertainties. In EFC, it is important to find the flux reference to
minimize power losses of induction motors. Therefore, we proposed
the optimal flux reference using the electrical power loss function.
The sliding mode flux observer is designed to estimate rotor fluxes
and variation of inverse rotor time constant. In RSC, the unknown
function approximation technique employs nonlinear disturbance
observer(NDO) using fuzzy neural networks(FNNs). The proposed
controller guarantees both speed tracking and flux tracking.
Simulation results are presented to illustrate the effectiveness of the
approaches proposed.
