|Title:||Direct-foc With Fuzzy Current Control For Asynchronous Machine|
Sguarezi Filho A.J.
|Abstract:||The conventional direct field oriented control scheme has two PI current controllers, and with the aim to reduce the quantity of these controllers, it is proposed a unique Fuzzy Current Controller (FCC) to substitute both PI controllers. The FCC calculates the quadrature components of the stator voltage vector, necessary to maintain the load. The rule base for the proposed controller is defined as a function of the stator current error components. The FCC takes trapezoidal and triangular membership functions for fuzzification of its inputs. The performance of the proposed FCC controller is analyzed through several tests such as: trapezoidal and triangular profile speed reversion, a step change in speed reference and a step change in the load reference with constant speed. The Experimental results show that the proposed FCC ensures decoupling current control and low current ripple, validating the proposed controller. © 2013 IEEE.|
