要約(日本語): In this study, IIR (Infinite Impulse Response) filters having a null frequency in the stop band region are designed using PSO (Particle Swarm Optimization). A new penalty function for forming a null is introduced to the objective function in addition to the conventional penalty function to ensure the stability of IIR filters. Such a constraint brings increments of the local minima in the solution space. Therefore, it is important to avoid the local minimum stagnation. We design IIR filters using PSO that reallocates particles when a local minimum stagnation occurs and verify the effectiveness of the method through several design examples.
