Design of an Anti-windup Fractional Order PI Controller based on Integral State Predictor within Stability Bound

摘要

In this paper, author proposed an Anti-windup FO-PI controller based on integral state predictor for speed control of variable speed motor drive. Controller gains are tuned by FOMCON toolbox using Nelder-Mead optimization topology where, initial range of controller gains are taken from stabilization curve. Performance of proposed topology and various anti-windup topology are evaluated and compared based on control effort, set-point tracking and performance indices such as ISE and IAE for both IO-PI and FO-PI controller. Result shows that proposed methodology provides smooth landing to its steady-state, when system comes from saturation to linear region with less control effort.
