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...

A Highly LinearLNA with Noise Cancellation for 5.8–10.6 GHz UWB Receivers

This paper presents a new ultra-wideband LNA which employs the complementary derivative superposition method in noise cancellation structure. A pMOS transistor in weak inversion region is employed for simultaneous second- and third-order distortion cancellation. Source-degeneration technique and two shunt inductors are added to improve the performance at high frequencies. The degeneration induc...

Cancellation 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...

Application 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...
