“…The idea of MTPC is to minimize the current amplitude for a certain torque, to reduce the copper losses in the stator windings. For this, the generally nonlinear flux linkage has to be known [1,[3][4][5].…”

This paper investigates efficiency enhancements in Permanent-Magnet Synchronous Machines (PMSMs) used as generators in wave energy converters. A method is presented, which allows experimental identification of the optimal current vectors leading to minimal losses and maximum efficiency. Iron and inverter losses are considered. The proposed identification method is generic and is applicable to any PMSM used as a generator. The obtained results are compared to the well-known Maximum Torque per Current (MTPC) strategy. Two MTPC strategies are investigated: (i) MTPC using linearised flux linkages; and (ii) MTPC using measured, nonlinear flux linkages. For both MTPC strategies, the influence of the Voltage Source Inverter (VSI) is taken into account. All measurements are performed on a simple and cheap industrial-like test bench. All three presented methods lead to increased efficiency. The best efficiency is obtained by the proposed maximum efficiency strategy, where iron and inverter losses are taken into account by proper measurement of the optimal current vectors.

This paper presents a new adaptive torque estimation algorithm for an interior permanent magnet synchronous motor (IPMSM) with parameter variations and cross-coupling between d-and q-axis dynamics. All cross-coupled, time-varying, or uncertain terms that are not part of the nominal flux equations are included in two equivalent mutual inductances, which are described using the equivalent d-and q-axis back electromotive forces (EMFs). The proposed algorithm estimates the equivalent d-and q-axis back EMFs in a recursive and stability-guaranteed manner, in order to compute the equivalent mutual inductances between the d-and q-axes. Then, it provides a more accurate and adaptive torque equation by adding the correction terms obtained from the computed equivalent mutual inductances. Simulations and experiments demonstrate that torque estimation errors are remarkably reduced by capturing and compensating for the inherent cross-coupling effects and parameter variations adaptively, using the proposed algorithm.

The salient effect of the rotor structure of the interior permanent magnet synchronous machine (IPMSM) makes it more suitable for running in the zone that exceeds the rated revolution by flux-weakening control. Therefore, the closed-loop speed regulation system composed by IPMSM can achieve excellent dynamic performance, high precision and wide speed performance. On the basis of the mathematical model of d / q coordinates of IPMSM, this paper discusses the control proposal of IPMSM: to control the current of d / q axis to maximize the speed range.
