Abstract
Dual-redundancy electromechanical servo actuation system used in the more electric aircraft servo actuation system has the advantages of both small size and high power density, and improves aircraft servo control system working reliability. Dual-redundancy permanent magnet brushless motor (DRPMBLM) used to realize electric energy to mechanical energy conversion is the key component, which directly affects the performance of the system. In this paper, The system topology is proposed by the analysis of the redundancy structure of DRPMBLM. The mathmatical models of pulse width modulation(PWM) converter model and state equations for DRPMBLM system were proposed. In these models, the mutual coupling for the mutual inductances between phases in each redundancy was considered. The simulation adapted to time-varying network model. By using this system model, the dynamic performance and characteristics for the DRPMBLM system were predicted and analyzed. Simulation and experimental results are compared in DRPMBLM system to verify the proposed modeling and characteristics analysis.
