    Loudspeaker Noise Disturbance Control Using Optimal and Robust Controllers.Mustefa Jibril, Messay Tadese & Fiseha Bogale - 2020 - Preprints 2020 (10):7.
    Noise reduction is the major issue in the loudspeaker for the application of the musical instruments and related areas. In this paper, a noise disturbance control of a loudspeaker with optimal and robust controllers has been done successfully. The noise of the loudspeaker has been analyzed by simply track a reference cone displacement with the actual cone displacement. Static output feedback and H infinity optimal loop shaping controllers have been used to compare the actual and reference cone displacements by using (...)

    Mechanically Actuated Capacitor Microphone Control Using MPC and NARMA-L2 Controllers.Mustefa Jibril, Messay Tadese & Eliyas Alemayehu - 2020 - Researcher Journal 12 (8):18-23.
    In this paper, a capacitor microphone system is presented to improve the conversion of mechanical energy to electrical energy using a nonlinear auto regressive moving average-L2 (NARMA-L2) and model predictive control (MPC) controllers for the analysis of the open loop and closed loop system. The open loop system response shows that the output voltage signal need to be improved. The comparison of the closed loop system with the proposed controllers have been analyzed and a promising result have been obtained using (...)
