Finite state machine control for aircraft electrical distribution system (2019)
Journal Article
Spagnolo, C., Sumsurooah, S., Hill, C. I., & Bozhko, S. (2019). Finite state machine control for aircraft electrical distribution system. Journal of Engineering, 2018(13), 506-511. doi:10.1049/joe.2018.0039

This study deals with the development of new control logic for more electric aircraft (MEA) electrical power systems (EPSs). A key aspect of the MEA concept is that traditional pneumatic and hydraulic loads are replaced by electrical equivalents. The... Read More

Starting an aircraft engine with an electrical machine has been one of the major trends for future aircraft. This paper studies the stability of a permanent-magnet machine (PMM) based aircraft starter/generator (S/G) system. Using control-to-output t... Read More

Comparative stability analysis of droop control approaches in voltage-source-converter-based DC microgrids (2016)
Journal Article
Gao, F., Bozhko, S., Costabeber, A., Patel, C., Wheeler, P., Hill, C. I., & Asher, G. (in press). Comparative stability analysis of droop control approaches in voltage-source-converter-based DC microgrids. IEEE Transactions on Power Electronics, doi:10.1109/TPEL.2016.2567780. ISSN 0885-8993

Droop control has been widely applied in DC microgrids (MGs) due to its inherent modularity and ease of implementation. Among the different droop control methods that can be adopted in DC MGs, two options have been considered in this paper; I-V and V... Read More

Dynamic phasor modelling of multi-generator variable frequency electrical power systems (2015)
Journal Article
Yang, T., Bozhko, S., Le-Peuvedic, J., Asher, G., & Hill, C. I. (2016). Dynamic phasor modelling of multi-generator variable frequency electrical power systems. IEEE Transactions on Power Systems, 31(1), doi:10.1109/TPWRS.2015.2399371. ISSN 0885-8950

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... Read More

Nonlinear aircraft engine model for future integrated power center development
Conference Proceeding
Enalou, H., Rashed, M., Kulsangcharoen, P., Hill, C. I., & Bozhko, S. (in press). Nonlinear aircraft engine model for future integrated power center development

Aircraft engines, the prime source of on-board power, play a vital role within the electrical power generation system. In literature these are considerably simplified to rudimentary engine speed. In this paper, a nonlinear zero-dimension (0-D) order... Read More
