The Dynamic Phasor (DP) concept has been widely used in modelling electrical power systems. So far, the DP concept has been restricted to modelling systems with one single electrical source at a fixed fundamental frequency; either one generator or an...

More electric aircraft starter-generator system with utilization of hybrid modulated model predictive control
Conference Proceeding
Yoeh, S. S., Yang, T., Tarisciotti, L., Hill, C. I., & Bozhko, S. (in press). More electric aircraft starter-generator system with utilization of hybrid modulated model predictive control.

The current trend for future aircraft is the adoption of the More Electric Aircraft (MEA) concept. The electrical based starter-generator (S/G) system is one of the core ideas from the MEA concept. The PI based control scheme has been investigated in... Read More about More electric aircraft starter-generator system with utilization of hybrid modulated model predictive control.
