Description: Improving dynamic response of DC-DC
converters which are nonlinear and complicate systems is an
interesting challenge in power electronics. This paper presents the
design and implementation of digital PID controller using the
chaotic particle swarm optimization (CPSO) for a Boost
converter and proposes an approach for auto tuning converter
optimum startup response. When the system starts, processor
unit analyses the open loop startup response of converter and
prepares optimum response during some iteration using CPSO
algorithm. Chaotic mapping using logistic map sequences
increases its convergence rate and resulting precision. Simulation
and Implementation results show efficiency of proposed
approach
