“…This decreases the voltage drop in the generator since the angle between the electromotive force (emf) and the current is decreased. In this paper, CTA control is implemented since it decreases copper losses in the generator [20] which usually are quite large in a direct-drive linear generator for wave power.…”

“…Please note that E f and I above are amplitudes and not phasors as for the CTA control the angle between them is zero. For a generator with surface-mounted magnets, i.e., a non-salient machine, the CTA control is very similar to the Maximum Torque per Ampere (MTPA) control [20]. As the name of the latter indicates, the CTA control will give lower current for a certain torque/force and therefore minimize the copper losses.…”

This paper presents a simulation method for direct-drive permanent-magnet linear generators designed for wave power. Analytical derivations of power and maximum damping force are performed based on Faraday's law of induction and circuit equations for constant-torque-angle control. Knowledge of the machine reactance or the load angle is not needed. An aim of the simulation method is to simplify comparison of the maximum damping force, losses, and cost between different generator designs at an early design stage. A parameter study in MATLAB based on the derived equations is performed and the effect of changing different generator parameters is studied. The analytical calculations are verified with finite element method (FEM) simulations and experiments. An important conclusion is that the copper losses and the maximum damping force are mainly dependent on the rated current density and end winding length. The copper losses are inherently large in a slow-moving machine so special consideration should be taken to decrease the end winding length. It is concluded that the design of the generator becomes a trade-off between material cost versus high efficiency and high maximum damping force.

“…The used approach employs an open-loop speed control and monitors the reactive power to regulate the current displacement. The MTPA system is almost exclusively implemented to control the IPMSM with high values of saliency ratio (> 2), since for machines with low values of saliency ratio, it seems not to produce substantial results [22][23]. Another reason that limited the use of the MTPA system in automotive and industrial applications is the complexity of this control system when compared with a traditional Field Orientation Control (FOC).…”

This paper deals with electrical drives employing low-saliency ratio interior permanent magnet synchronous motors. In particular, in order to help the designers choosing the best control algorithm, the performances of the Maximum Torque Per Ampere Control (MTPA) and the Field Orientation Control (FOC) are here both theoretically and experimentally assessed and compared, by using, as performance indicators, the torque-current ratio and the power losses. The tests are carried out on a low-power motor for various speeds and loads by implementing the two control strategies in a dSPACE ® rapid prototyping system. The results show that the Maximum Torque Per Ampere algorithm has some appreciable advantages mainly for high load conditions of operation.
