Abstract In critical industrial applications fault diagnosis and tolerance are considered key features, in order to ensure the required reliability availability levels. this context, paper proposes a new effective diagnostic algorithm for power semiconductors open‐circuit faults, three‐phase, two‐level, voltage‐source inverter‐fed permanent magnet synchronous machine (PMSM). The proposed method is based on analysis of errors between reference currents PMSM stator predictive currents. Hence,...
Availability and continuous operation under critical conditions are very important in electric machine drive systems. Such systems may suffer from several types of failures that affect the or associated voltage source inverter. Therefore, fault diagnosis tolerance highly required. This paper presents a new robust deep learning-based approach to diagnose multiple open-circuit faults three-phase, two-level inverters for induction-motor applications. The proposed uses fault-diagnosis variables...
This paper presents an improved model predictive control (MPC) for permanent magnet synchronous motor (PMSM) fed by a voltage source inverter (VSI), in order to reduce switching losses. The MPC strategy is based on cost function generally established performance purposes and leads states be applied VSI control. In this work, the changing so Simulations are carried out illustrate theoretical development results demonstrate effectiveness of proposed approach.
