IIR Filter Design Using Cat Swarm Optimization
Yuta Harigae, Kenji Suyama · IEEJ Transactions on Electronics Information and Systems · 2020
Design of IIR filters using PSO (Particle Swarm Optimization) has been proposed. However, an objective function of the design problem has a shape like a saddle point under the min-max criterion, and it causes one of the factors of the stagnation. In this paper, a design method IIR filters using CSO (Cat Swarm Optimization) is proposed for a succesive search. The design examples are shown to present the effectiveness of the proposed method.
