Abstract: In this paper, the optimisation of the PID controller employing the PSO algorithm for the interleaved buck-boost power converter is outlined. Currently, buck-boost power converters are broadly used in several application areas like the photovoltaic system, uninterruptable power supplies, and electric vehicle. The buck-boost power converter can be connected in parallel with one or more other buck-boost converters (multi phasing) or the interleaved configuration so less filtering requirement to suppress the ripple is needed and the effective resultant frequency is increased and thus high reliability and efficiency for the power converter is achieved. The switching pulses for these converters are sequenced or interleaved in time to give the required phase shift between the interleaved buck-boost converters. The control circuit for this interleaved buck-boost converter is tuned by the PSO algorithm. The system is tested firstly by changing the input voltage and secondly by changing the output load resistance. The Simulations and the operational dynamical performance of the interleaved buck-boost converter with PID controller employing PSO algorithm results are executed using MATLAB software.

Keywords: interleaved buck-boost converter; PID controller; buck-boost converter; particle swarm optimisation; PSO; state space.
