To develop a speed control framework for IPMSM electric vehicles that enhances stability during field-weakening operations.
Proposed a stability-aware adaptive framework that integrates fractional-order PI control, fuzzy gain-scheduling, and multi-objective optimization.
Conducted qualitative analysis using Lyapunov methods.
Optimized controller parameters using fractional-order multi-objective PSO algorithm.
Achieved a zero-overshoot transient response under field-weakening constraints.
Demonstrated 82% reduction in speed RMSE compared to conventional methods.
Lowered current THD from 18.5% to 3.2% and reduced DC-link current-squared index by 6.7%.
