Abstract

The position control of hydraulic front end loader while dealing with unknown external load disturbances is the focus of this paper. The simulation results obtained show that the type-2 fuzzy controller is capable of minimizing the position error of a front end loader’s bucket under load variations. This kind of hydraulic system is highly nonlinear due to factors such as leakage and friction. There are uncertainties in this system due to temperature dependence of bulk modulus and fluid viscosity. Such uncertainties together with the load variations cause chattering of the bucket position. Simulation results show for positional error of boom cylinder while varying the load in the bucket and also 50 to 150% of variation in the nominal value of bulk modulus.
