A Digital Pole Placement Approach to Control an Electrohydraulic Servo-Valve using a PMTM Actuator

Hydraulic actuators are prevalence to their admirable mechanical characteristics such as ability to impose large forces quickly and there for are dramatically required at industrial applications. At the 20th century, the servo hydraulic valves were invented in order to supply more sophisticated motions but still more precise and less powered electrical actuators are preferred at more accurate manipulations because of the hydraulic systems which are not enough punctual. The main reason for this is the lack of required control performance at usual traditional analogue proportional integral derivative (PID) control strategies implemented at hydraulic actuators. In this study, a new discrete domain pole placement strategy is suggested to cover more elaborated applications.
