Leaky Partial Update LMS Algorithms Project Details
| Abstract |
Multichannel structural active noise control (ANC) systems are highly effective for global noise reduction, but their practical implementation is often constrained by extreme computational demands. This research-based project framework explores the application of Partial Update (PU) adaptive algorithms to mitigate these computational bottlenecks in structural ANC. Specifically, the work focuses on the integration of leaky variants of PU Least Mean Square (LMS) algorithms, which introduce a leakage factor to stabilize the adaptive filter coefficients against numerical drift and excitation issues common in structural plants. The project provides structuring and implementation guidance for modeling these algorithms within a multichannel framework. By updating only a subset of the filter coefficients at each
sampling interval, the computational complexity is significantly reduced without severely compromising the noise attenuation performance. The methodology is evaluated using simulation models derived from real laboratory setups, allowing for a comparative analysis of convergence rate, steady-state error, and computational savings between standard LMS, leaky LMS, and the proposed leaky PU-LMS variants. This resource serves as a technical reference for M.Tech students developing simulation models and evaluating adaptive signal processing strategies for structural vibration and acoustic control.
