This file contains a model of a backhoe arm built using Simscape. The hydraulic actuation system, including pump, valves, and hydraulic cylinders, actuates the arm and bucket. The three-dimensional mechanical system is modeled, including the arm joints and bucket linkage. Examples in this submission show how to model custom hydraulic valves, tune controller and physical system parameters, and generate C code from the entire model.
