Abstract

Conventional derivative based learning rule poses stability problem when used in adaptive identification of infinite impulse response (IIR) systems. In addition the performance of these methods substantially deteriorates when reduced order adaptive models are used for such identification. In this paper the IIR system identification task is formulated as an optimization problem and a recently introduced cat swarm optimization (CSO) is used to develop a new population based learning rule for the model. Both actual and reduced order identification of few benchmarked IIR plants is carried out through simulation study. The results demonstrate superior identification performance of the new method compared to that achieved by genetic algorithm (GA) and particle swarm optimization (PSO) based identification.

► Cat swarm optimization based approach for IIR system identification. ► Cat swarm optimization is more efficient than GA and PSO. ► This algorithm is tested on standard IIR plants. ► Sensitivity analysis of different parameters on the performance of CSO algorithm.
