Active Noise Cancellation System for UAVs
نویسندگان
چکیده
The aim of this Project is to complete a first study of Active Noise Cancellation systems applicability to Unmanned Aerial Vehicles. The main motivation to this research is the EASA request to minimize noise from UAVs in populated areas, besides all other possible applications. At first, a brief introduction to the issue and ANC systems is made. Then, a physical model of propellers soundwaves is carried out so that an estimation of noise cancellation levels is possible. Next chapters are focused in the system employed. An algorithm is selected, modelled, and studied. Same steps are made with microprocessor, microphone and speakers. Principal research conclusions are discussed within the last section: this first study corroborates the feasibility of using ANC systems in order to reduce noise generated by UAVs. Finally, future work lines are proposed.

Active Noise Cancellation using Online Wavelet Based Control System: Numerical and Experimental Study
Reaction wheels (RWs) used for attitude control of space vehicle systems usually encounter with undesired wide band noises. These noises which significantly affect the performance of regulator controller must tune the review or review rate of RWs. According to wide frequency band of noises in RWs the common approaches of noise cancellation cannot conveniently reduce the effects of the noise. Th...

متن کاملCancellation of Series-Loss Resistance in UWB Active Inductors using RC Feedback
One of the most important features of the Active Inductors (AIs) is their input equivalent resistance, namely series-loss resistance, which should be low enough to have a high Quality Factor (QF). Most of the previous methods by this goal did not yield a high enough QF. This paper presents a new method, namely applying an RC feedback, to cancel series-loss resistance entirely. As the RC fee...
متن کاملApplication of High Order X - LMS Filter for Active Noise Control
In this paper active noise is controlled by using higher order X-LMS (least mean square) filter. This technique is based on X-NLMS (normalized least mean square), also known as traditional acoustic noise cancellation (ANC) scheme. It cancels the wideband noise from the corrupted speech signal. The active noise reducing headphone is probably the most successful application of active control of s...
