Optimal and automated decentralised converter control design in more electrical aircraft power electronics embedded grids

چکیده
In modern power systems, the proliferation of electronics converters, and distributed generation raises important issues concerning inter-connected switching units in terms performance, stability robustness. Such phenomenon are more prominent micro-grids, such as local low voltage distribution electric aircraft systems etc., where many converters connected to same non-stiff ac grid, strongly interact with each other. Locally designed converter control on electrical bus exhibit interactive behaviour. If not taken properly into account, external disturbances system at given operating conditions may result degradation failure meet and, some cases, instability. This paper presents a new approach synthesise controllers grids (which is, however, applicable all embedded systems), keeping consideration dynamic interactions among subsystems. An optimal design based H2 optimisation is therefore proposed. Phase-locked loops have also been considered, their tuning has included general procedure whole system. Simulation, experimental results show good improvements interaction mitigation.

Integrated optimal design for power systems of more electrical aircraft
this paper proposes an optimal design approach that aims at coupling a set of design models with an optimization algorithm in order “to improve the integration” of electrical devices and systems embedded in more electrical aircraft. This approach has already been applied to relatively complex power conversion systems like an electrical air conditioning system (ECS) and its interest has been pro...

متن کاملA Review on VHF Power Electronics Converter and Design Issues
high output power density VHF converter has become important in recent years. This output power density of the converter is experiencing an adverse effect resulted from the applied switching frequency. In addition, the frequency which is higher than 20 MHz will no longer be applicable on the discreet SMT technology hence lowers the output power density. Thus, further improvement on circuit anal...
