Experimental study demonstrates improved torque tracking in predictive synchronous motor drives using trigonometric current mapping, indicating enhanced robustness against parameter variations.

Key Points

To investigate the sensitivity of MTPA-guided model predictive control drives to electrical parameter variations and develop a parameter-independent MTPA trajectory strategy.
Evaluated conventional MTPA and cost-function-based MTPA under stator inductance and flux linkage variations across both model predictive current control (MPCC) and model predictive torque control (MPTC) schemes.
Formulated an experimental MTPA framework relying on trigonometric current mapping to generate optimal dq-axis current references without relying on motor electrical parameters or weighting factor adjustments.
Validated the control algorithm experimentally on a 4.1-kW interior permanent magnet synchronous machine drive platform.
Identified that parameter mismatch within MTPA reference calculation produces more severe torque tracking degradation than the internal parameter dependency of the MPC algorithm itself.
Demonstrated superior torque tracking accuracy and heightened resilience to parameter drift with the trigonometric mapping strategy compared to conventional and cost-function-based MTPA methods.
