Electric circuit parameters identification and control strategy of dual-rotor Permanent Magnet Induction Machine

Abstract

This paper presents the steady-state per phase equivalent electric circuit of the dual-rotor Permanent Magnet Induction Machine (PMIM), a method for the identification of parameters and a control strategy using a co-simulation between a FEM software and system simulation software. In order to develop a control strategy for the dual-rotor PMIM, one needs to estimate first the electric parameters (resistances, reactances) of the per-phase equivalent electric circuit. Each parameter of the circuit is discussed separately and comparative analytical and numerical techniques are proposed for their computation. Then, a two loops control strategy of the machine based on the Field Oriented Control (FOC) and Scalar Control (SC), is proposed and applied to the PMIM.
