Abstract
A new technique to design accurate, stable, and wideband infinite impulse response, fractional order digital integrators (FODIs) for the fractional order integrators based on a metaheuristic optimization technique called artificial raindrop algorithm (ARA) is proposed in this paper. ARA is inspired by the process of natural rainfall, and achieves the global optimal solution by identifying the raindrop which occupies the lowest altitude. To investigate the efficiency of the proposed approach, comparisons have been carried out with real coded genetic algorithm, particle swarm optimization, and differential evolution-based FODIs. Simulation results demonstrate that ARA-based FODIs consistently accomplish better magnitude responses in the least number of iteration cycles. The proposed FODIs also outperform all the recently reported designs.
