   Energy efficient control of induction motor servo drives with optimized motion and flux trajectories
By Frederik KLENKE, Wilfried HOFMANN [View]
[Download]

Abstract: This paper presents the effect of energy efficient control strategies on positioning processes of induction motor servo drives. In comparison to conventional trajectories that operate at constant rated flux optimized motion and flux trajectories lead to a significant reduction of energy losses in the drive system.

   High efficiency rectifier for a variable speed transverse flux permanent magnet generator for wind turbine applications
By Mehdi TAGHIZADEH KAKHKI, Maxime DUBOIS [View]
[Download]

Abstract: An uncontrolled bridge rectifier could not be used with a transverse flux machine due to its high stator reactance. A high efficiency rectifier topology is introduced which could be used with sources with variable frequency and high source inductance including transverse flux machines.

   Multi-fidelity Simulation Modelling in Optimization of a Hybrid Submarine Propulsion System
By Arturo MOLINA-CRISTOBAL, Patrick R. PALMER, Geoffrey T. PARKS [View]
[Download]

Abstract: Multi-objective Genetic Algorithms have become a popular choice to aid in optimising the size of thewhole hybrid power train. Within these optimisation processes, other optimisation techniques for thecontrol strategy are implemented. This optimisation within an optimisation requires many simulationsto be run, so reducing the computational cost is highly desired. This paper presents an optimisationframework consisting of a series hybrid optimisation algorithm, in which a global search optimizes asubmarine propulsion system using low-fidelity models and, in order to refine the results, a local searchis used with high-fidelity models. The effectiveness of the Hybrid optimisation algorithm is demonstratedwith the optimisation of a submarine propulsion system.
