A self-tuning feedforward active noise control system
This paper proposes a self-tuning feedforward active noise control (ANC) system with online secondary path modeling. The stepsize parameters of the controller and modeling filters have crucial rule on the system performance. In literature, these parameters are adjusted by trial-and-error. In other words, they are manually initialized before system starting, which require performing extensive ex...
متن کاملA Self-tuning Feedback Active Noise Control System
Active Noise Control (ANC) systems are developing rapidly because of their improvements in environmental noise reduction. ANC is based on either feedforward or feedback control. Feedback structures are employed in applications that the reference signal is not available. The step size of filters used in ANC systems plays an essential role in performance of the system. Any variation from the appr...
متن کاملAnalysis and design of narrowband active noise control systems
This paper presents an analysis and optimization of narrowband active noise control (ANC) systems using the liltercd-X least mean-square &MS) algorithm. First, we derive an upper bound for the eigenvalue spread of the filtered reference signal’s covariance matrix, which provides insights into algorithm convergence speed. Amplitude of internally generated sinusoidal reference signal is optimized...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولSelf-learning active noise control.
An important step for active noise control (ANC) systems to be practical is to develop model independent ANC (MIANC) systems that tolerate parameter variations in sound fields. Reliabilities and stabilities of many MIANC systems depend on results of online system identifications. Parameter errors due to system identifications may threaten closed-loop stabilities of MIANC systems. A self-learnin...
