Speed Control of dc Motor using dc to dc Converter(Boost Converter)

Abstract

The project is designed to the switched-mode dc-dc converters are some of the most widely used power
electronics circuits for its high conversion efficiency and flexible output voltage. These converters used for electronic
devices are designed to regulate the output voltage against the changes of the input voltage and load current. This leads
to the requirement of more advanced control methods to meet the real demand. Many control methods are developed for
the control of dc-dc converters. To obtain a control method that has the best performances under any conditions is
always in demand.
Conventionally, the dc-dc converters have been controlled by linear voltage mode and current mode
control methods. These controllers offer advantages such as fixed switching frequencies and zero steady-state error and
gives a better small-signal performance at the designed operating point.. These controllers are robust concerning
converter parameter variations, load and line disturbances. SM controlled converters generally suffer from switching
frequency variation when the input voltage and output load are varied. This complicates the design of the input and
output filters. The main objective of this research work is to study different control methods implemented in dc-dc
converter namely (linear controllers, hysteresis control, and current programmed control.
