Smith chart-based PSO algorithm for multi-objective engineering problems

Abstract

In this study, a new approach based on the Smith chart is proposed for multi-objective particle swarm optimization. With this approach, the position of each particle is updated according to the Smith chart’s impedance and admittance circles to determine the local best particle. The proposed method is applied to three test functions with different behaviors, namely concave, convex, and non-convex, and performance parameters are examined. In light of the obtained results, it has been observed that the proposed strategy offers successful convergence performance for multi-objective optimization applications and meets performance expectations with its obtained well-distributed solution set.
