Harmonic distortion reduction of commercial airplane electrical power system using fuzzy logic based current control of active power filter

Abstract

Summary In this study, a novel method is proposed for current control (CC) of an active power filter (APF) of the aircraft power system, which is based on a fuzzy inference system (FIS). The control system is designed according to the instantaneous power theory. Two other conventional CC methods consisting of the hysteresis current control method (HCCM) and adaptive hysteresis current control method (AHCCM) are utilized in the study and their results are compared with the proposed fuzzy current control method (PFCCM). It is shown that the proposed method is more successful in eliminating harmonics without drawbacks of conventional methods such as high and variable switching frequency which hardens system design and utilization. The study is carried out in MATLAB\Simulink environment to prove the applicability of the proposed method.

Fuzzy Bayesian based bow-tie risk assessment of runway overrun: a method for airline flight operations

“…Fuzzy logic has been introduced in many engineering-related fields in aviation. Aircraft conflict resolution (Sathyan et al , 2017), unmanned aerial vehicle swarm routing (Sathyan et al , 2016), aerodynamic modeling (Chang, 2013), fuzzy logic controller to drive autopilot altitude in landing phase (Rawea and Urooj, 2015) and harmonic distortion reduction (Radmanesh and Gharehpetian, 2021) are only a few examples of fuzzy logic implementation in the aerospace industry. In addition to engineering applications, fuzzy logic is also widely used in risk assessment applications in aviation.…”
