ADAPTIVE CONTROLLER FOR DC MOTOR DRIVES: A HARDWARE AND SOFTWARE APPROACH

F I Ahmed, A M El-Tobshy, A A Mahfouz, and M M Ibrahim
Faculty of Engineering, University of Cairo, Egypt



Abstract:

The most commonly used controller for the speed control of dc motor drives is (P-I) controller. In spite of the major features of the (P-I) controller, it has some disadvantages such as: the high starting overshoot in speed, the sensitivity to controller gains and the sluggish response due to sudden change ....etc

Real-Time Positioning Technology Fleet management system is a rapid growing industry. This system helps institutions to manage vehicle fleet efficiently and effectively through smart allocation of resources. In this project, an intelligent fleet management system which incorporates the power of concurrent Global Positioning System (GPS) and Global System for Mobile Communications (GSM) real-time positioning, front-end intelligent and web-based management software is proposed. In contrast to systems which depend solely on GPS positioning, the pr ....etc

This work proposes a new, software-based, defect detection and diagnosis technique. We introduce a novel set of instructions, called Access-Control Extensions (ACE), that can access and control the microprocessor s internal state. Special firmware periodically suspends microprocessor execution and uses the ACE instructions to run directed tests on the hardware. When a hardware defect is present, these tests can diagnose and locate it, and then activate system repair through resource reconfiguration. The software nature of our framework makes i ....etc
