The Effects Of Parameter Variation In Open-Loop And Closed-Loop Control Scheme For An Electro-Hydraulic Actuator System

It is well known that the EHA system is exposed to the disturbances,uncertainties,and parameter variations which are caused by the changes in operating conditions for instance,total moving mass,supply pressure,servo-valve gain,bulk modulus,leakage coefficient,and friction.These problems pose to a gr...
