Nonlinear Control System Design for Active Lubrication of Hydrostatic Thrust Bearing

The active controlled hydrostatic bearing is becoming more and more popular because of its accuracy, safety, as well as low vibration and noise. In this paper, we present a design approach for a hydrostatic thrust bearing system, where the analytical nonlinear state space equation of the system is e...
