Modeling a Hydraulic Actuation System   7:02

This video demo shows how to model a hydraulic actuation system using SimHydraulics. A double-acting hydraulic cylinder is controlled by a four-way directional valve.

Modeling a Custom Hydraulic Valve   9:42

In this video demo, we show how to use Simscape to model a four-way hydraulic valve and a hydraulic cylinder. Hydraulic and mechanical physical modeling building blocks are used to build this model.

Simscape Language: Hydraulic Example   5:27  

This video demo shows how to model custom hydraulic components using the Simscape language. We build a model of a fixed hydraulic orifice using this MATLAB-based physical modeling language.

Estimating the Parameters of a Hydraulic System   4:32

In this video demo we show how you can use optimization algorithms to obtain realistic parameter values for a hydraulic cylinder. Parameter values will be tuned automatically until simulation results match measurement data.

Integrating Physical Systems and Controller   5:50  

This video demo shows how to detect integration issues in simulation. Models of mechanical, hydraulic, electrical, and control systems are gradually integrated into a full system model, enabling engineers to test systems in isolation and to test overall system performance.

Logging Simulation Data   3:11  

This video demo shows how to automatically log all simulation data from the physical system to the MATLAB workspace. You can post-process and analyze data from all portions of the physical network without adding additional sensors to your model.

Optimizing System Performance   6:08  

This video demo shows how to use optimization algorithms to automatically tune the performance of a hydromechanical pitch control system until it meets system requirements.

Hydraulic Valve Parameters, Orifice Area   8:03  

This video demo shows how to use optimization algorithms to tune hydraulic valve parameters so that simulation results match flow rate characteristics on manufacturers data sheets.

Hydraulic Valve Parameters, Transient Response   4:57  

This video demo shows how to use optimization algorithms to tune hydraulic valve parameters so that the transient response in the simulation matches characteristics on manufacturers data sheets.

Hydraulic Valve Parameters, Frequency Response   6:51  

This video demo shows how to use optimization algorithms to tune hydraulic valve parameters so that the frequency response of the model matches frequency response characteristics on manufacturers data sheets.

Analyzing and Documenting Results   4:02  

This video demo shows how to automatically run tests and generate a report documenting simulation results. The Simulink Report Generator is used to run tests, evaluate performance, and to capture screenshots of the model and simulation results into a document.

Using Local Solvers for Real-Time Simulation   4:22  

This video demo shows how to configure local solvers on your physical networks to minimize computations during fixed-step simulations. Combining these solvers enables this model to run in real time.

Simulating In Real Time: Hydromechanical Example   5:40  

This video demo shows how to configure solver settings to enable SimHydraulics and SimMechanics models to execute in real time. Both global and Simscape local solvers are configured, and the model is downloaded to a real-time target.

Hardware In The Loop (HIL) Testing   5:21  

This video demo shows how to use HIL testing instead of hardware prototypes to test control algorithms. A Simulink model using MathWorks physical modeling tools is converted to C code and downloaded onto Bachmann electronic M1 hardware controller.

Protecting Intellectual Property in Subsystems   4:39  

This video demo shows how to protect the contents of a subsystem containing physical modeling components. The resulting subsystem can be shared for simulation and parameter testing without exposing intellectual property.

Protecting Simscape Language Components   2:31  

This video demo shows how to convert your Simscape language source code to a binary format so that you can share them with other engineers without exposing your intellectual property.
