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.

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.

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.

Abstract: Advances in computers and communication technology have changed traditional methods for learning and skills training. Today, distance learning is becoming an increasingly popular alternative to traditional programs.

A fuzzy decision making process is used to update the leaner model and specify his/her learning level to provide appropriate teaching materials to each learner. Such a system can deal with uncertainties in the learner’s degree of understanding in each unit. It provides a powerful educational tool that can assist the learner to move from one learning unit to the other according to his/her learning level.
