Abstract

This paper proposes an analytical method to determine maximum torque per ampere (MTPA) trajectories in the voltage plane for interior permanent magnet synchronous machines (IPMSMs). The MTPA is formulated as an optimization problem and its solution is obtained within a closed-form function, from the current and voltage planes. In consequent, the MTPA tracking control strategy with the novel closed-loop direct voltage control is developed for the IPMSM drive systems. Comparison studies against the well-known conventional current regulation-based MTPA tracking control strategy illustrate the superiority of the developed strategy in various aspects as well as its efficient MTPA tracking capability. Furthermore, it also shows more robustness to the IPMSM's parameter variations than conventional strategy from voltage constraint point of view.
