Fuzzy Logic Based-Active Fault Tolerant Control of Speed Sensor Failure for Five-Phase PMSM
Yemna Bensalem,Rabeh Abbassi,Houssem Jerbi 대한전기학회 2021 Journal of Electrical Engineering & Technology Vol.16 No.1
The present study seeks to investigate the problem of fault tolerant speed control of the fi ve-phase Permanent Magnet Synchronous Motor (PMSM) in the presence of speed sensor fault. Indeed, the sensors which are the most sensitive elements play a signifi cant role in the closed loop control. In this context, an active Fault Tolerant Control (FTC) is developed based on fuzzy controller. Using the Sliding Mode Observer (SMO), the reconfi guration scheme which alternates between the measured speed value and the estimated one is proposed during failure occurrences so as to preserve the best control performance. The fi ve-phase PMSM is monitored by a fuzzy logic controller to reduce disturbances that can occur under fault conditions. The two techniques which are used to illustrate consistency in the proposed approach are the following: the sliding mode with encoder or without encoder-based control and the fuzzy logic control for effi cient decision sent to the fi eld-oriented control. Simulation tests, in terms of the measured and the estimated speed responses, have been carried out on the fi ve phase PMSM drive. The results demonstrate that the proposed FTC scheme can validate the proposed FTC strategy and guarantee service continuity.

This paper presents a new control strategy which is based on a switching table applied for Virtual FluxDirect Power Control (VF-DPC) of voltage source inverter based shunt active power filter (SAPF). This controlmethod is applied to eliminate harmonic pollution and compensate the reactive power in the presence of nonlinearloads and unbalanced sources. Its main goal is to select switching states of the SAPF converter appropriately basedon a look-up table established by hysteresis controllers acting on the instantaneous error between the commandedand VF-estimated values of active and reactive power. Our method aims to improve the electrical quantity behaviorin steady and dynamic states while reducing the installing cost of the filter through eliminating the AC line voltagesensors. Facing to disturbances affecting the electrical network, a phase locked loop (PLL) has been integrated .Thecontrol strategy proposed for the active filter has been tested in the Matlab/Simulink environment.
