The rapid advancements in induction motor drives has led to the development of robust non-linear controller such as Fuzzy Logic Controller (FLC). The proportional integral or derivative controllers (PI, PID, and PD) have been in use for induction motor drives for past decades as speed and current controller's. However, these controllers are fixed to motor parameter changes which results in decrease...
Measurements of cooling power and heat demand are presented for an adsorption heat pump (AHP) that integrated a finned adsorbent heat exchanger and a solar collector. For this study the adsorbent heat exchanger was heated/cooled with fluid at near constant temperature. Results from a bench scale, large temperature jump (LTJ) test were scaled to predict the outcome of a larger experiment (adjusting...
This paper presents the performance evaluation of Voice over Internet Protocol (VoIP) in Multi-hop Wireless Network (MWN) developed using Multi-radio Access Relay (MAR). The MWN is deployed using 3 MARs in Universiti Teknikal Malaysia campus. The performance of VoIP are investigated using Real Time Protocol (RTP) and Compress Real Time Protocol (CRTP) header techniques. RTP and CRTP are used to transport...
Task assignments to team of homogenous autonomous robots are in research trends in robotic field. Autonomous homogeneous multi-robot is known to have similar architecture in terms of structure and identical control system as well as their tasking. At present, most research of multi-robot mainly focuses on motion control layer. Nevertheless, a successful control and coordination of a group of robot...
