Figure 3 Visualization of an Operating Point

Any operating point of an Multi-Input Multi-Output earthmoving powertrain (See Introduction) can be visualized in a two-dimensional picture. In Fig. 1, the (speed, torque) plane of the engine and the (flow, pressure) plane of the pump are put in the same plot. In this way, we can observe at the same time the operating conditions of the engine in the mechanical domain,  and the operating conditions of the pump, valves and loads in the hydraulic domain. (In this example, a simple linear engine model instead of a realistic one is used, which is enough to discuss different input effects.)
