<p>In previous work, the design method of IIR filters using PSO (Particle Swarm Optimization) has been proposed. However, it is known that an objective function of the design problem has a region like a saddle point and a lot of local minimums under the min-max criterion. Those characteristics cause one of the factors of the stagnation. In this paper, a design method IIR filters using PSO with penalty and CSO (Cat Swarm Optimization) is proposed for enumerating a lot of local minimums and a succesive search in such the region. Design examples are shown to present the effectiveness of the proposed method.</p>
