Abstract: This paper presents a web-based laboratory for
distance learners by incorporating simulation and
hardware implementation into web-based e-learning
systems. It presents a development consisting of laboratory

properly in order to achieve the experiment objective. The
proposed laboratory e-learning tool has web-based
components accessed by authorized users. Learners can
acquire the necessary skills they need, while learning the
theory of the experiment and the basic characteristics of
each component used in the experiment. Finally, a case

Research Title: Fuzzy-Based Decision Making
Author: Kasim Mousa Al-Aubidy, Published Year: 0
Faculty: Engineering and Technology
Abstract: Several efforts have been made to develop computer-based learning
and training systems. However, computer animation alone will not
provide users with opportunities to obtain real-sense learning/training
and develop their skills. For that reason, there is a need to explore more
advanced technologies to improve learning and training. Virtual reality
has found a number of applications in learning and skills training.
Real educational processes deal with uncertainty in human
knowledge. Most of available educational systems use classical
methods to handle vague information in the knowledge representation
and decision making. Furthermore, fuzzy set theory incorporates
precise techniques for solving such problems. Fuzzy logic concepts
have been used in ESs for knowledge representation and reasoning.
Fuzzy logic is the most suitable tool to deal with vague knowledge
and the process of decision making in the educational system.

Research Title: Fuzzy logic control implementation in sensorless PM drive systems
Author: Kasim Mousa Al-Aubidy, Published Year: 0
Faculty: Engineering and Technology
Abstract: The PM motor drive systems are becoming particularly popular in
many industrial applications. They have many of the desirable
performance characteristics of both the AC and DC drive
systems. In this paper, a fuzzy logic controller is proposed for the
real-time control of a Sensorless PM drive system. An implicit
detection method has been used to detect the rotor position and to
measure both the rotating speed and internal load angle. The
results given in this paper demonstrate the capability of such a
drive system in applications where simplicity, reliability and
stability are more important issues. Furthermore, the proposed
hardware and software design is simple and can be implemented
by a single-chip microcontroller for real-time applications.

Research Title: FPGA-Based Fuzzy Inference System for Real-time Embedded Applications
Author: Kasim Mousa Al-Aubidy, Published Year: 0
Faculty: Engineering and Technology
Abstract: The traditional way of implementing algorithms in software limits the performance of
real-time systems, since the data is processed serially. The new generation of FPGAs with embedded
processors are attracting the interest of the real-time applications. With enhanced capabilities most of
the processing tasks can be loaded from the software program stack to embedded processors on the
FPGA to improve performance and reduce the cost of the whole system. A fuzzy inference system
has been implemented on an FPGA, and used to control a PM motor in a washing machine. The
given results demonstrate the capability of such embedded controller in washing machine
applications where simplicity, reliability and stability are more important issues.

Research Title: Fast Power Loss Computation and Shunt Capacitor Insertion Using Fuzzy Logic Technique
Author: Kasim Mousa Al-Aubidy, Published Year: 0
Faculty: Engineering and Technology
Abstract: Fast power loss computation was implemented using supervisory control and data
acquisition system (SCADA) with personal computer. Logic Control Array (LCA) and EPROM
circuits were used to implement SCADA system to facilitate the required measurements to obtain the
daily load profile for residential and commercial customers. LCA, EPROM and PC were used to
simplify the electronic circuits, reduce the cost and speed up the computation time.
An illustrative example had been considered to measure, store and show the active power, reactive
power, load voltage, load current, power factor and the shunt capacitors current. It as observed that
when 2.7 MVAR bank capacitor inserted in the network the load current decreased from 740.8A to
688.4A and the power factor was improved from 0.80 to 0.93, which reduced the apparent power,
hence allowing to add more loads to the network and release the feeder capacitor. A rule-based fuzzy
decision maker had been designed and tested with the real data collected from Jordan electricity board
using SCADA system. The calculated output was almost similar to that obtained from the first
approach presented in this study. The advantage of using fuzzy decision maker was its simplicity that
can be implemented on a programmable logic device.

Research Title: Fast Energy Loss Computation and Fuzzy-Based Shunt Capacitor Insertion
Author: Kasim Mousa Al-Aubidy, Published Year: 0
Faculty: Engineering and Technology
Abstract: Fast energy loss computation is implemented using supervisory control and data
acquisition system (SCADA) with personal computer. Logic Control Array (LCA) and
EPROM circuits are used to implement SCADA system and to measure the Volt-
Ampere, KVolt and KVAR and draw the daily load curve for residential and commercial
customers. LCA, EPROM and PC are used to simplify the electronic circuits, reduce the
cost and speed up the computation time.
An illustrative example was done to measure, store and show the active power, reactive
power, load voltage, load current, power factor, and the shunt capacitors current. It is
found that when 2.7 MVAR bank capacitor is inserted in the network the load current is
decreased from 740.8A to 688.4A and the power factor is improved from 80% up to 93%,
and led to add more loads on the network and release the feeder capacitor.
A rule-based fuzzy decision maker has been designed and tested with the real data
collected from Jordan using SCADA system. The calculated output is almost similar to
that obtained from the first approach presented in this paper. The advantage of using
fuzzy decision maker is its simplicity that can be implemented on a programmable logic
device and can be programmed to improve the power factor.
