Adaptive Internal Model Control Based on Parameter Adaptation
Chen, Peng; Zhang, Yunfeng; Wang, Jianhong; Azar, Ahmad Taher; Hameed, Ibrahim A.; Ibraheem, Ibraheem Kasim; Kamal, Nashwa Ahmad; Abdulmajeed, Farah Ayad (Peer reviewed; Journal article, 2022)In actual industrial control, many objects have the characteristics of large lag and time-varying parameters, which makes it difficult for traditional PID control to obtain satisfactory control effects. Therefore, engineers ... -
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 ... -
