Interval system analysis and PID-PSO control of boost converter for uncertain load parameter

This paper deals with the characteristics of a Boost Converter in the presence of uncertain load parameters. An Interval System analysis is adopted to evaluate the interval extension of load parameters and then a PID controller is designed using Particle Swarm Optimization(PSO). The PID-PSO controller meets the requirement of robust design and the design specification is satisfied over the entire parameter set. The particle swarm optimization (PSO) method is used to determine near optimum PID controller parameters assuring improved response for uncertain load parameters. Here, all the analyses have been done for continuous conduction mode (CCM) mode of operation and simulation results are plotted in MATLAB.
