Abstract: The trend towards the adoption of direct drive washing machines utilizing PM motors is increasing due to the mechanical simplicity, high performance and efficiency of the system. This work deals with design and performance of a sensorless PM motor drive for washing machines. An implicit rotor position detection unit which consists of groups of search coils are inserted into the motor stator. A simple neuro-fuzzy controller has been used. The results given in this paper demonstrate the capability of such a drive system in washing machine applications where simplicity, reliability and stability are more important issues.

Abstract: This paper is concerned with the design and development of a simple fuzzy system for modeling of ill-defined dynamical systems. This system, which is represented as a feed forward neural network, is able to incorporate qualitative and quantitative information. Supervised linear back propagation learning algorithm has been applied to model a system through identifying the fuzzy parameters. This adaptive fuzzy system is implemented as an identifier of dynamical systems. The system performance has been evaluated for different simulated systems to demonstrate the application of the proposed system to identify the dynamics of linear and nonlinear time-invariant and time-variant systems.

Abstract: A new hierarchical model based on CPN for general FMS scheduler is presented. The designed model is partitioned into two levels to face the complexity of the manufacturing systems. The first level in the model is the cell-level, which supervises the jobs scheduling between cells. The second level is the machinelevel, which supervises the scheduling of the manufacturing jobs between machines inside the active cells. The goal of the model is to interpret the output of the manufacturing route planner into graphical representation and to achieve the sequencing, dispatching and monitoring the real time execution of these manufacturing plans. Also the proposed CPN model generates feedback status to monitor the abnormal conditions. Sub CPN priority structures are embedded in the main model to control the election from the competitive jobs to use the limited resources in the system. The hierarchy organization will enhance the real time response of the sequencing and monitoring capabilities. The designed scheduler has been evaluated for different case studies and the achieved results are very encouraging.

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.

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.
