| 摘 要： | INTRODUCTION Electro hydraulic servo systems (EHSS) havebeen used in industry in a wide number of applica-tions due to their small size-to-power ratio and theability to apply very large force and torque. How-ever, the dynamics of hydraulic systems are highlynonlinear (Merritt, 1967), the system may be sub-jected to non-smooth and discontinuous nonlin-earities due to control input saturation, directionalchange of valve opening, friction, and valve overlap.Aside from the nonlinear na…
