A Neural Network Based Speed Control Of A Linear Induction Motor Drive, Adel A. Elbaset, Ahmed A. Hassan, Yehia S. Mohamed, T. Hiyama,, T. H. Mohamed

Dr. Adel A. Elbaset

In this paper, a general regression neural network (GRNN) based controller is used to control the speed and thrust output of the linear induction motor drive. The field orientation principle is used to asymptotically decouple the motor speed from the secondary flux. The idea of model predictive control technique is used for the training of the proposed controller. The motivation for using this control strategy for training the GRNN based controller is to reduce the effect of the uncertainty due to motor parameters variation and load disturbance. This newly developed design strategy combines the advantage of the neural networks and …

Coping With The Curse Of Dimensionality By Combining Linear Programming And Reinforcement Learning, Scott H. Burton May 2010

Coping With The Curse Of Dimensionality By Combining Linear Programming And Reinforcement Learning, Scott H. Burton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reinforcement learning techniques offer a very powerful method of finding solutions in unpredictable problem environments where human supervision is not possible. However, in many real world situations, the state space needed to represent the solutions becomes so large that using these methods becomes infeasible. Often the vast majority of these states are not valuable in finding the optimal solution. This work introduces a novel method of using linear programming to identify and represent the small area of the state space that is most likely to lead to a near-optimal solution, significantly reducing the memory requirements and time needed to arrive …

Rethinking The Business Model Concept With Eparticipation, Mutaz M. Al-Debei, Panagiotis Panagiotopoulos, Guy Fitzgerald, Tony Elliman

Dr. Mutaz M. Al-Debei

Enhancing citizen participation in policy making using Information and Communication Technologies (ICTs) is emerging as a strategic issue for political organisations. ICT-mediated participation, or eParticipation, projects range from the more traditional public sector initiatives, such as petitions and consultations, to attempts at integrating new forms of participatory Web 2.0 media. In this paper, we argue that the potential of ICTs to deliver sustainable eParticipation has not been fully achieved. This is mainly because of the lack of (1) effective coordination at the implementation level, (2) appropriate infrastructure, and (3) effective service design and development. In addressing this gap, we examine …
