Field programmable gate array-based sensorless control of a brushless synchronous starter generator for aircraft application

Safety-critical power conversion systems play a major role in the paradigm shift towards more electric aircraft (MEA) architectures. This paper reviews the electrical machines and their power electronic systems that are currently competing in the application of integrated starter-generators (S/Gs) in MEA power systems. Motivated by the strict requirements of sufficient electrical starting capability, super-high power density and ultra-high reliability, additional considerations on the overall system design are necessary, including the power electronic converters (PECs) and integrated thermal designs. These aspects are discussed not only in the light of their many benefits but also of the challenges introduced by the continuous advancements and emerging innovations in the power conversion technology. In achieving the MEA goals and capitalize on all potential benefits, optimization-based design approaches will be necessary, where the aggregation of electric machines, PECs and the aircraft grid is considered as an integrated system to be optimized. This review highlights the importance of these aspects and offers a view on future perspectives and open issues.

Abstract. Based on the mathematical model of synchronous electric machine, basing on permanent magnets, presented in this paper, the key importance of alternator AC power sources in the form of generator (for conventional aircraft) and in the form of integrated unit starter/AC synchronous generator S/G AC (with respect to advanced aircraft concept in the field of more/all electric power MEA/AEA) was highlighted. In addition, through the analysis and selected simulations of the power supply system of a modern aircrafts, sources of onboard electrical energy (synchronous generator, integrated unit starter/AC generator) were located in board autonomic power system ASE (EPS, PES). Key components of this system are the electro-energetic power system EPS and the energo-electronic power system PES. Additionally, the analysis and exemplary simulations of key electricity sources based on mathematical models have contributed to highlighting the main practical applications in line with the trend of a more electric aircraft.

“…In addition, due to the ripples of excitation current, traditional sensorless control technologies cannot be readily applied to S/G [5]- [9].There are few literatures on the sensorless control of S/G. Reference [10] presents a sensorless method based on back electromotive force voltage estimation, which has good performance in the high speed region. But the scheme in low speed region is not given.…”

This paper proposes a sensorless control method for Wound-Rotor Synchronous Starter/Generator (WSSG) in starting process. It is necessary to identify the initial rotor position when uses sensorless control method to start-up AC machines. However, during the process of initial orientation the excitation current of the main generator contains severe pulsating components, which leads to the ineffectiveness of traditional position estimating methods. In order to improve the accuracy of estimation results, the specified transient pulse signal voltage injection and the associated signal processing method are propose in this paper. In starting process, the square-wave-type voltage signal injection method, which capably of eliminates the interference of pulsating excitation current and enhancing the dynamic performance of the system, is used in the starting process to acquire the rotor position by demodulating the induced high-frequency stator current. Experimental results proved the effectiveness and accuracy of the propose method.
