Development of a Novel Disturbance Observer Based Fractional Order PD Controller for a Gun Control System

Development of a Novel Disturbance Observer Based Fractional Order PD Controller for a Gun Control System

Motion control of gun barrels is an ongoing topic for the development of gun control equipment (GCE) with excellent performances. In this paper, a novel disturbance observer (DOB) based fractional order PD (FOPD) control strategy is proposed for the GCE. By adopting the DOB, the control system behav...
