The increased penetration of distributed generators in power systems with the transport electrification trend combined with significant advances in power electronics and control has led to DC systems being proposed for applications such as microgrids, electric vehicles and more-electric aircrafts and ships. Stability, where for example, oscillations in the DC-bus voltage exceed protection levels causing the network to be disconnected, was identified as one of the main issues related with DC systems due to the increase in dynamic interactions in multi-converter networks. System stability degradation due to constant power loads was especially highlighted. Constant power loads often consist of tightly regulated power converters and motor drives. In this thesis, active stabilisation control techniques for a field oriented controlled induction motor drive connected to a feeder system, are proposed. An impedance-based stabilisation control is first considered and a tuning method based on an impedance stability criterion, enabling a control design in term of stability margins, is proposed. The control is thoroughly analysed using frequency-domain and time-domain simulations. A passivity-based stabilisation control is then proposed. The control scheme is derived from an energy principle, which enables a more intuitive tuning procedure, whilst still providing a design in term of stability margins by the means of a phase compensator. Extensive frequency-domain and time-domain simulations of the stabilisation control are presented. Both stabilisation strategies are implemented on a low cost digital signal controller and are then demonstrated, evaluated and compared using a control hardware-in-the-loop emulation platform. The active stabilisation controls exhibit a significantly improved system relative stability whilst minimising the degradation of the system performance. Control sensitivity to parameter and design errors is carefully investigated. Finally, the benefits and limitations of each stabilisation scheme are discussed.
