In this paper, the authors develop innovative methodology for robust and stable design of digital Infinite Impulse Response (IIR) filters using a heuristic search method. The proposed heuristic search method enhances the capability to explore and exploit the search space locally as well globally to obtain optimal filter design parameters. A multi-criterion optimization is employed as design criterion to obtain optimal stable IIR filter that satisfies different performance requirements like minimizing Lp-norm approximation error and ripple magnitude.
