Design and Implementation of a Speed-Loop-Periodic-Controller-Based Fault-Tolerant SPMSM Drive System

Abstract

This paper proposes a speed-loop periodic controller design for fault-tolerant surface permanent magnet synchronous motor (SPMSM) drive systems. Faulty conditions, including an open insulated-gate bipolar transistor (IGBT), a short-circuited IGBT, or a Hall-effect current sensor fault are investigated. The fault-tolerant SPMSM drive system using a speed-loop periodic controller has better performance than when using a speed-loop PI controller under normal or faulty conditions. The superiority of the proposed speed-loop-periodic-controller-based SPMSM drive system includes faster transient responses and better load disturbance responses. A detailed design of the speed-loop periodic controller and its related fault-tolerant method, including fault detection, diagnosis, isolation, and control are included. In addition, a current estimator is also proposed to estimate the stator current. When the Hall-effect current sensor is faulty, the estimated current is used to replace the current of the faulty sensor. A 32-bit digital signal processor, type TMS-320F-2808, is used to execute the fault-tolerant method and speed-loop periodic control. Measured experimental results validate the theoretical analysis. The proposed implementation of a fault-tolerant SPMSM drive system and speed-loop periodic controller design can be easily applied in industry due to its simplicity.

Speed‐loop frequency‐adaptive and current‐loop optimal harmonic periodic controllers for fault‐tolerant SPMSM drive systems

“…The parameters of the FAPC, such as a control gain and a phase‐lead compensator , are determined using stability analysis in the closed‐loop control system. The detailed analysis is shown in reference [14] and is omitted here by the authors due to the limitation of scope. By using this similar method, we can obtain parameters of the controller, which are shown in Figure 6.…”

Revitalisasi Pembangkit Listrik Tenaga Surya (Plts) Pada Sistem Microgrid Pulau Tomia

“…Terdapat beberapa peneliti yang sudah membahas sistem microgrid, dimulai dari pemanfaatan baterai sebagai penyimpan energi (Mckeon et al, 2013;Serban et al, 2013), fungsi baterai sebagai penyangga frekuensi maupun tegangan jika terjadi perubahan yang signifikan pada pembangkit dan beban (Bae et al, 2012;Xia et al, 2019), pembahasan sistem kontrol pengaturan daya pada inverter (Che et al, 2015;Jiang et al, 2007;Patarroyo-montenegro et al, 2017;Wang et al, 2011;Zhao et al, 2015;Liu et al, 2019), serta manajemen energinya (Dong et al, 2020;Jos et al, 2020). Namun, belum ditemukan artikel yang membahas mengenai proses revitalisasi suatu aset microgrid yang sedang mengalami permasalahan.…”
