Hydro+pneu: A quasi realtime hydraulic and pneumatic system simulation package
Tony Wong, Pascal Bigras, Daniel Cervera · 2001
Hydraulic and pneumatic systems are highly nonlinear and difficult to analyze. This paper presents a quasi real-time simulator designed for efficient numerical simulation of hydraulic and pneumatic systems. This simulator uses a bond-graph theoretic approach for system equation formulation. A highly optimized and stabilized iterative integrator ensures accurate numerical solution of the system equations. Coupled to the integrator's output is a graphical animation subsystem. The latter is responsible for rendering movable components on screen at every simulation time-step. Thus, creating the illusion of continuous movement. An important characteristic of this simulator is its ability to permit in-simulation manipulation that allows user to interact with circuit components while a simulation run is in progress.
