Abstract:
In this paper, the author has focussed on the
detailed modeling and analysis of a variant of cuk converter
i.e. Interleaved Cuk converter (ICC), which along with having
the benefits of conventional cuk converter also provide additional
advantages of ripple cancellation, increased current and voltage
rating thereby high rating applications can be successfully taken
advantage of. Feedback control is a part of any stable system and
to gain desired response, a progressive optimization algorithm
which is the Genetic Algorithm (GA) is used here to tune the
control variables; PID control gains and additional freedom
of control are present where fractional order PID (FOPID)
controller variables λ and µ can be utilized with the traditional
PID controller for the desired response. The simulation results are
presented for servo and regulatory response, parameters current
and voltage results along with the results when variations are
subjected to the input voltage as well as the reference voltage.
The results confirm the desired results are obtained with the
ripples confined to 1% and settling of the output voltage at the
setpoint value
