Maximum Torque per Ampere Control for Interior Permanent Magnet Motors Using DC Link Power Measurement
Maximum torque per ampere (MTPA) control scheme for internal permanent magnet (IPM) machine is presented in this paper. Proposed control scheme was developed based on measurement of only DC link quantities eliminating the necessity of 3-phase current feedback. The scheme employs an online search algorithm with initial condition computed from a-priory system information. Hybridization of search based algorithm with pre-computed control coefficients ensures robustness against parameter variations while maintaining good dynamic performance.
