Especially for you Andreas Ardhus, Project Engineer as well as our tutor at Saab, for your supervision and guidance; Johan Nordling, Consultant at Siemens In...

Belt Conveyor Dynamics in Transient Operation for Speed Control

Abstract—Belt conveyors play an important role in continuous dry bulk material transport, especially at the mining industry. Speed control is expected to reduce the energy consumption of belt conveyors. Transient operation is the operation of increasing or decreasing conveyor speed for speed control. According to literature review, current research rarely takes the conveyor dynamics in transien...

RELIABILITY OF LARGE SCALE CONVEYOR SYSTEMS A Simulation Approach

The overall performance of industrial conveyor systems for bulk depends on the reliability of individual system components and their arrangement. A model for dimensioning of large scale systems in the early design stage is discussed. In the model discrete event simulation is used for the modelling of equipment reliability and simple numerical integration is applied for the stacking and loading ...

Design and Simulation of Double Loop Control for Power Converter Fed Variable Speed DC Drive

Modeling, Simulation and Control of Matrix Convert for Variable Speed Wind Turbine System

This paper presents modeling, simulation and control of matrix converter (MC) for variable speed wind turbine (VSWT) system including permanent magnet synchronous generator (PMSG). At a given wind velocity, the power available from a wind turbine is a function of its shaft speed. In order to track maximum power, the MC adjusts the PMSG shaft speed.The proposed control system allowing independen...
