Parameters Identification for Control Tuning with Offline Methods for Permanent Magnet Synchronous Machines

Inhalt:
This paper proposes an offline method to identify the electrical and mechanical characteristic parameters of Permanent Magnet Synchronous Machines (PMSMs). The proposed sequential method identifies the electrical parameters, such as the stator resistor and dq-axes inductances, the electromagnetic parameters, such as the flux constant, and the mechanical parameters, such as friction and inertia. The main objective is to automatically determine the parameters of the current, speed, and flux-weakening (FW) regulators from these parameters. The achieved error with the proposed method is less than 2% concerning the actual values. Simulation results verify the effectiveness of the proposed methodology.
