Abstract

Abstract : DC – DC power supplies are playing significant role in different domains of engineering applications. Some converters such as boost, buck‐boost, and fly‐back have a right‐half‐plane zero (non‐minimum phase system), hence it is difficult for the PID controller to exhibit good performance with load, line variations and parametric uncertainty. In this proposed work, design and implementation of type controllers have been performed by using k ‐factor approach and two different optimisation techniques (gravitational search algorithm and particle swarm optimisation) for obtaining better stability and performance for a closed loop DC–DC Switched mode boost converter. The closed loop control system has been implemented in real time dSPACE platform. The comparative closed‐loop performances of a boost converter with classical, optimised PID and optimised type II/type III controllers have been produced. Simulations and experimental results are provided to demonstrate the effectiveness of optimised controllers for the proposed converter. Design and implementation of optimised type controller for switch mode converters has not been reported earlier in any literature.
