An analytical study of bifurcation and nonlinear behavior of indirect filed-oriented control induction motor
نویسندگان
چکیده
This paper deals with an analytical investigation of the nonlinear behavior of an indirect filedoriented control of induction motor. In this context, steady-state solutions in mathematical model of this machine are discussed and an analytical study of the generic codimension one bifurcation, Hopf and Fold bifurcations, was made. Of special interest here is the codimension two bifurcation namely a Double Hopf bifurcation. The purpose of this paper is to present some elementary mechanisms of such singularities, to derive some analytical rigorous existence conditions and to develop an algorithm for their detection. Key–Words: Dynamical behavior, Bifurcation, Chaos, Induction motor, PI Controller gains.

The main purpose of this paper is to give a reasonably comprehensive discussion of what is commonly referred to as the bifurcation analysis applied to an indirect field oriented control of induction machines (IFOC). In the current work, we study the appearance of self-sustained oscillations in AC drives and compute their corresponding stability margins. As the dynamics is explored, a transition...

This paper proposes a new sliding mode control (SMC) based model reference adaptive system (MRAS) for sensorless indirect field oriented control (IFOC) of a single-sided linear induction motor (SLIM). The operation of MRAS speed estimators dramatically depends on adaptation mechanism. Fixed-gain PI controller is conventionally used for this purpose which may fail to estimate the speed correctl...
