Overview

Simulation study demonstrates improved transient performance in doubly salient permanent-magnet motors using fuzzy-PI control, indicating an effective alternative to complex drive algorithms.

Key Points

Establish a control-oriented nonlinear model using finite-element analysis and evaluate a fuzzy-PI speed controller for a 12/8-pole doubly salient permanent-magnet motor.
Constructed a nonlinear model for a 12/8-pole DSPM motor using 3D lookup tables in the stationary αβ frame to capture flux-linkage Jacobians, rotor-position derivatives, and electromagnetic torque.
Accounted for magnetic saturation, armature reaction, interphase coupling, and simultaneous nonzero phase currents via finite-element analysis.
Designed a closed-loop drive featuring an outer fuzzy-PI speed loop with nonlinear gain scheduling and an inner current hysteresis loop, benchmarking performance against a conventional PI controller.
The FEA-derived stationary αβ lookup tables successfully captured complex nonlinear magnetic interactions and commutation-dependent characteristics.
The fuzzy-PI speed controller achieved superior transient response and performance compared to the conventionally tuned PI controller under identical conditions.
