| Summary: | DC-DC Boost Converter and Hybrid Posicast Controller is developed and simulated
using MATLAB Simulink software. DC-DC Boost converter has a very high
overshoot and a very high settling time which produce oscillated output response. In
order to overcome this weakness, Hybrid Posicast Controller is used in order to
regulate the output voltage to a desire value. Hybrid Posicast Controller operated
within the feedback loop of the system. Transfer function of DC-DC Boost Converter
are derived and Posicast elements of
and
Td
can be calculated directly from the
transfer function. Single gain,
K
is used in order to eliminate the overshoot and
minimize the settling time. Simulation results show that Hybrid Posicast Controller
effectively regulate the output voltage to a desire value even though load resistance
and duty cycle have been changed with a various values. DC-DC Boost Converter
using Posicast Controller has an excellent performance to overcome unregulated
