Research of the dynamic performance of DC servo control system based on Fractional Order PIλDμ

Due to greater flexibility and wider adaptability, the fractional order PI^λD^μ controller has been drawn more attention by more researchers. However, there is less research of improving specific dynamic performance of servo system by far. For a typical DC servo system, the fractional order PI^λD^μ is designed in this paper, and the improved chaotic particle swarm optimization algorithm is also used to set the parameters. At the same time, under the requirements of dual-ten index, the bandwidth of the feed forward controller and the PID controller of the DC servo system are compared, of course the comparison and analysis of the velocity and acceleration at the same bandwidth. The simulation results show that, the DC servo system of fractional order PI^λD^μ controller has better dynamic performance.
