SimHydraulics
Model and simulate hydraulic systems
SimHydraulics® provides component libraries for modeling and simulating hydraulic systems. It includes models
of hydraulic components, such as pumps, valves, actuators, pipelines, and hydraulic resistances. You can use these
components to model fluid power systems such as front-loader, power steering, and landing gear actuation
systems. Fuel supply and water supply systems can also be modeled using SimHydraulics.
SimHydraulics models can be used to develop control systems and test system-level performance. You can
parameterize your models using MATLAB® variables and expressions, and design control systems for your
hydraulic system in Simulink®. You can add electrical, mechanical, pneumatic, and other components to your
hydraulic model using Simscape™ and test them in a single simulation environment. To deploy models to other
simulation environments, including hardware-in-the-loop (HIL) systems, SimHydraulics supports C-code
generation.

Modeling a Hydraulic Actuation System 7:01
Model a hydraulic actuation system. A double-acting hydraulic cylinder controlled by a
four-way directional valve is modeled using SimHydraulics® components.

SimHydraulics is used to optimize system-level performance and to create plant models for control design. The
models you create support your entire development process, including hardware-in-the-loop simulations.
