Robustness margins for indirect field-oriented control of induction motors
The influence of the rotor time constant mismatch on the stability of induction motors under indirect field-oriented control is analyzed. The results of [14] are generalized. A Lyapunov function which provides a global stability test and allows us to compute robustness margins is given. Different mechanisms for the loss of stability are detected by means of bifurcation analysis. Robustness marg...
متن کاملRobustness of global asymptotic stability in indirect field-oriented control of induction motors
The influence of the rotor time constant mismatch on the global stability of induction motors under indirect field oriented control (IFOC) is analyzed. A test for global stability is provided, based on necessary and sufficient conditions for the existence of quadratic Lyapunov functions for IFOC drives. This test yields robustness margins with respect to rotor time constant mismatches. A typica...
متن کاملGlobal asymptotic stability of indirect field-oriented speed control of current-fed induction motors
In this short paper, we show that the indirect field-oriented controller for currentfed induction motors guarantees the global asymptotic stability of speed tracking error for time-varying speed and rotor flux references. The load torque is assumed to be constant but is unknown.
متن کاملAn indirect adaptive neuro-fuzzy speed control of induction motors
This paper presents an indirect adaptive system based on neuro-fuzzy approximators for the speed control of induction motors. The uncertainty including parametric variations, the external load disturbance and unmodeled dynamics is estimated and compensated by designing neuro-fuzzy systems. The contribution of this paper is presenting a stability analysis for neuro-fuzzy speed control of inducti...
متن کاملIndirect Flux-Oriented Control of Faulty Single-Phase Induction Motors
Most types of electrical machines such as Induction Motors (IMs) can be modeled by an equivalent 2-phase machine (d-q model). For instance a single-phase IM with two main and auxiliary windings can be modeled as an equivalent 2-phase IM. Also a faulty single-phase IM (single-phase IM under open-phase fault) can be modeled as an unbalanced 2-phase IM. This study confirms this concept by modeling...
