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

Simulation Investigations of Electrohydraulic Drive Controlled by Haptic Joystick∗∗

In the paper a control of electrohydraulic drive made by human operator which uses a special haptic joystick is presented. On the basis of main equations describing electrohydraulic drive, its simulation model is proposed. To this model a simplified model of human operator is added. The paper presents the system stability problem which can occur when in communication with operator, force feedba...

Review of Variable Speed Drive Technology By

Variable speed drive technology has advanced dramatically in the last 10 years with the advent of new power devices and magnetic materials. This has given rise to substantial confusion by users and specifiers of variable speed drive equipment. Add to that the difficulty in evaluating efficiency and power factor and the subject of drive selection becomes a daunting task indeed. There is no singl...

Modern Topology& Thermal Analysis of Drive for Variable Speed Pumped Storage Power Plant

Given the significant power generation and consumption of variable-speed pumped storage power plants (VSPSPs), it is crucial to enhance drive methods and decrease drive losses, thereby increasing productivity. This paper proposes the topology for VSPSP drivers with two level voltage source converters (2LVSC) with 6+1 converters. Hydraulic and electrical VSPSP models are presented, following whi...

Variable Speed Drive Application Based Acoustic Noise Reduction Strategy

The acoustic sound level caused as secondary effects of industrial energy conversion processes is often perceived as an unwelcome noise emitted into the enclosing surrounding. In order to verify design aspects for reducing such undesirable noise emission in particular within variable electric speed drive applications, suggested novel combinations of electrical and mechanical motor topologies ar...
