• Design and Stability Analysis of Sliding Mode Controller for Non-Holonomic Differential Drive Mobile Robots 

      Azar, Ahmad Taher; Abed, Azher M.; Abdul-Majeed, Farah Ayad; Hameed, Ibrahim A.; Jawad, Anwar Ja’afar Mohamad; Abdul-Adheem, Wameedh Riyadh; Ibraheem, Ibraheem Kasim; Kamal, Nashwa Ahmad (Peer reviewed; Journal article, 2023)
      This paper presents a novel extended state observer (ESO) approach for a class of plants with nonlinear dynamics. The proposed observer estimates both the state variables and the total disturbance, which includes both ...

    • A New Nonlinear Dynamic Speed Controller for a Differential Drive Mobile Robot 

      Hameed, Ibrahim A.; Abbud, Luay Hashem; Abdulsaheb, Jaafar Ahmed; Azar, Ahmad Taher; Mezher, Mohanad; Jawad, Anwar Ja’afar Mohamad; Abdul-Adheem, Wameedh Riyadh; Ibraheem, Ibraheem Kasim; Kamal, Nashwa Ahmad (Peer reviewed; Journal article, 2023)
      A disturbance/uncertainty estimation and disturbance rejection technique are proposed in this work and verified on a ground two-wheel differential drive mobile robot (DDMR) in the presence of a mismatched disturbance. The ...
    • Parameterization of a Novel Nonlinear Estimator for Uncertain SISO Systems with Noise Scenario 

      Azar, Ahmad Taher; Abdul-Majeed, Farah Ayad; Majdi, Hasan Sh.; Hameed, Ibrahim A.; Kamal, Nashwa Ahmad; Jawad, Anwar Jaafar Mohamad; Abbas, Ali Hashim; Abdul-Adheem, Wameedh Riyadh; Ibraheem, Ibraheem Kasim (Peer reviewed; Journal article, 2022)
      Dynamic observers are commonly used in feedback loops to estimate the system’s states from available control inputs and measured outputs. The presence of measurement noise degrades the performance of the observer and ...
