Abstract

The paper presents a simple and effective direct flux and torque control strategy for the active minimization of torque ripple in Permanent Magnet synchronous motor drives. The observed stator flux amplitude and the estimated electromagnetic torque are directly controlled, and the torque feedback is estimated through a pre-determined 3D Look-UpTable having the (d, q) current components and the measured rotor phase angle theta as inputs. The torque LUT used in the paper was obtained via dedicated preliminary experimental tests, but other methods for its determination exist, including Finite Element Analysis where possible, and manipulation of the flux d, q linkage characteristics. Simulation and experimental results are provided for a 10kW Permanent Magnet Synchronous Motor to demonstrate the validity of the proposed torque control strategy.
