3. An improved torque control strategy of “five-phase PMSG-PWM rectifier” set for marine current turbine applications

Increasing the phase number of the generators improve the fault tolerance of the electrical energy production system in marine current applications. This paper deals with torque control strategy of five phase PMSG-PWM rectifier set. Based on Fortescue transformation a dynamical model of “five phase PMSG non sinusoidal EMF” in natural basis is established. In order to maximize the average torque, to minimize the copper losses and to reduce the torque ripples all harmonics of EMF are exploited for the normal operation mode. Thus, an adequate stator phase current waveforms are synthesized in natural basis (abcde). To ensure an effective tracking of these currents waveforms a robust nonlinear model-free controller with a large bandwidth is proposed. Simulation and experimental results highlight the performances of the control strategy and co
