Salient brushless AC (BLAC) permanent magnet (PM) motors are a preferred topology in the rapidly growing area of electric vehicle traction due to their inherent high efficiencies and excellent power densities. In the design of these systems it is important to appraise the motor performance across the entire torque-speed envelope. This paper presents computationally efficient techniques that all...

This paper aims to introduce two new adaptive designs of vibration control systems. First is an absorber and the second is an isolator. Absorbers are used for suppressing unwanted vibrations, while isolators isolating them. Structural parameter changes and excitation directions significantly affect the behavior of the conventional passive controllers. A Tuned Stiffness Damper (TSD), stepper mot...

As, the number of vehicles are increased day by day in rapid manner. It causes the problem of traffic congestion, pollution (noise and air). To overcome this problem A FPGA based parking system has been proposed. In this paper, parking system is implemented using Finite State Machine modelling. The system has two main modules i.e. identification module and slot checking module. Identification m...

The development and implementation of an FPGA neural network control system for motion control is a task that requires techniques and methods from several engineering fields. In this paper is presented the design of a microprocessor-based neural control system for the realization of the control of a stepper motor for a manipulator arm. The application circuit developed is a specific design of a...

We investigated experimentally the frequency dependence of a superconducting vortex ratchet effect by means of electrical transport measurements and modeled it theoretically using the time-dependent Ginzburg-Landau formalism. We demonstrate that the high frequency vortex behavior can be described as a discrete motion of a particle in a periodic potential, i.e., the so-called stepper-motor behav...

Hands-on laboratory instruction is essential to improve student learning in engineering education. In the area of CAD/CAM/Manufacturing Technology lab courses, the high cost of commercial CNC machines like mills and lathes limits the quantity of machines accessible to the students. In this paper, a low-cost, build-your-own (BYO) three axis vertical computer numerical control (CNC) mill prototyp...
