Abstract
Although high bandwidth for the pressure tracking of hydraulic actuators is highly desirable in many industrial applications, it has been a challenge to achieve, mainly due to the natural velocity feedback path in these actuators. In this paper, we investigate the extent to which a fixed-gain linear controller designed based on quantitative feedback theory (QFT) can improve the pressure tracking bandwidth while considering other design criteria including closed-loop stability, disturbance rejection, and robust tracking. Simulation and experimental results are presented to demonstrate that the designed QFT controller satisfies the mentioned design criteria over a wide range of parametric uncertainties, and at the same time provides 6 Hz pressure tracking bandwidth.
