 Abstract

This paper proposes a fast dynamic DC-link voltage control strategy for dual three-phase permanent-magnet-assisted synchronous reluctance starter/generator (DTP-PMa-SRS/G) system. First, the model of a DTP-PMa-SRS/G is analyzed considering its asymmetric structure. A power balance strategy is adopted to solve the coupling problem between two sets of windings. Then the power model of the starter/generator system is analyzed considering the disturbance caused by inherent parameter uncertainty and external load variation. To improve the dynamic response performance of the DC-link voltage, an integral terminal sliding-mode DC-link voltage controller (ITSMVC) with an extended state observer (ESO) is proposed. The system stability is verified by Lyapunov theory. A simple parameter design method for the proposed ESO-ITSMVC is adopted to ensure satisfactory performance. Finally, a comparison of experimental results with the conventional ITSMVC, the active-disturbance rejection controller (ADRC), and the disturbance observer-ITSMVC (DO-ITSMVC) is carried out. The superior DC-link voltage dynamic response performance of the proposed method is verified.
