Dynamics and Control of Quadcopter Using Linear Model Predictive Control Approach
Research Output | Dar Al-hikmah Library | IIUM Only

This paper investigates the dynamics and control of a quadcopter using the Model Predictive Control (MPC) approach. The dynamic model is of high fidelity and nonlinear, with six degrees of freedom that include disturbances and model uncertainties. The control approach is developed based on MPC to track different reference trajectories ranging from

Cfd Analysis of Sd 7003 Airfoil at Low Reynolds Number with a Laminar Kinetic Energy Based Transition Model
Research Output | Dar Al-hikmah Library | IIUM Only

The characteristics of laminar separation bubbles (LSBs) on the SD 7003 airfoil have been extensively studied in the past at low Reynolds numbers. It has been found that the LSB is extensive, especially at airfoil at angle of attack (α) of 4º. To analyze separation, transition and reattachment of flow around SD 7003 airfoil effectively, Computati

Trajectory Tracking in Quadrotor Platform by Using Pd Controller and Lqr Control Approach
Research Output | Dar Al-hikmah Library | IIUM Only

The purpose of the paper is to discuss a comparative evaluation of performance of two different controllers i.e. Proportional-Derivative Controller (PD) and Linear Quadratic Regulation (LQR) in Quadrotor dynamic system that is under-actuated with high nonlinearity. As only four states can be controlled at the same time in the Quadrotor, the traject

Development of Enzymatic Pretreatment of Palm Oil Mill Effluent for Monomers Towards Biogas Production
Research Output | Dar Al-hikmah Library | IIUM Only

In anaerobic digestion for enhancement of biogas production, various types of pre-treatment method have been used with some limitations in terms of sustainable environmental management. Although acid and alkali pretreatment have a significant effect on the degradation of biomass, these methods have some negative impacts on the environment due to th

The Spread of Islam in India and Southeast Asia
Research Output | Dar Al-hikmah Library | IIUM Only

The ancient maritime trading links enabled by the seasonal monsoons between East Africa and China, via the Arabian, Indian and Southeast Asian ports, have played an important but overlooked role in the history of human civilization. The coastal regions of the Indian Ocean represent a cosmopolitan blend of social and cultural diversity enriched main

A Study of Accountability Practice in Dompet Dhuafa Waqf of Indonesia
Research Output | Dar Al-hikmah Library | IIUM Only

The aim of this study is to address the issue of accountability practice in a waqf institution. Specifically, the focus of this study is to provide insights into how accountability is perceived and discharged by the mutawallī (waqf trustee) in managing a waqf. In so doing, a case study of one Indonesian waqf institution, that is, Dompet Dhuafa is

Miniaturized Water Flow and Level Monitoring System for Flood Disaster Early Warning
Research Output | Dar Al-hikmah Library | IIUM Only

This study presents the performance of a prototype miniaturised water flow and water level monitoring sensor designed towards supporting flood disaster early warning systems. The design involved selection of sensors, coding to control the system mechanism, and automatic data logging and storage. During the design phase,the apparatus was constructed
