Abstract
Speed ripple at lowspeed-high torque operation of PermanentMagnet SynchronousMachine (PMSM) drives
is considered as one of the major issues to be treated. The presented work proposes an efficient PMSMspeed
controller based on Grey Wolf (GW) algorithm to ensure a high-performance control for speed ripple reduction
at low speed operation. The main idea of the proposed control algorithm is to propose a specific objective
function in order to incorporate the advantage of fast optimization process of the GW optimizer. The
role of GW optimizer is to find the optimal input controls that satisfy the speed tracking requirements. The
synthesis methodology of the proposed control algorithm is detailed and the feasibility and performances of
the proposed speed controller is confirmed by simulation and experimental results. The GW algorithm is a
model-free controller and the parameters of its objective function are easy to be tuned. The GWcontroller is
compared to PI one on real test bench. Then, the superiority of the first algorithm is highlighted.
