DC Motor Damping: A Strategy to Increase Passive Stiffness of Haptic Devices

Physically dissipative damping can increase the range of passive stiffness that can be rendered by a haptic device. Unlike simulated damping it does not introduce noise into the haptic control system. A DC motor can generate such damping if it’s terminals are shorted. We employ a configuration of the H-bridge which can cause this damping to impart stability to our haptic device. This results in...

Boost Converter for Power Factor Correction of DC Motor Drive

With the increasing demand for power from the ac line and more stringent limits for power quality, power factor correction has gained great attention in recent years. A variety of circuit topologies and control methods have been developed for the PFC application. While the discontinuous conduction mode (DCM) converters such as boost and flyback converters are well suited for low power applicati...

Fuzzy Remote Controller for Converter Dc Motor Drive

In this paper fuzzy speed and current controllers are proposed for closed loop speed control of a converter fed dc motor drive. The performance of the fuzzy controlled system is compared with that of P-I controlled system to establish its suitability. The controller is implemented in a 486 based PC, and attempt is made to control the motor from a remote operating point via FM transmitter and re...

DC / DC Converter for Motor Drive - Concept , Design , and Feed - Forward Control

Solar photovoltaics is one of the most promising technologies for the non-carbon based electricity production. Power electronics is therefore necessary. In this paper a converter is analyzed which makes it possible to control the mean value of the output voltage, this is e.g. the voltage across a DC machine (and therefore the speed) from zero up to three times of the input voltage. The converte...
