Modeling a Hydraulic Actuation System   7:02

Model a hydraulic actuation system. A double-acting hydraulic cylinder controlled by a four-way directional valve is modeled using SimHydraulics components.

Modeling a Custom Hydraulic Valve   9:42

Model a custom four-way hydraulic valve and a hydraulic cylinder using Simscape Foundation Library blocks.

Simscape Language: Hydraulic Example   5:27  

Model custom mechanical components using the Simscape language. A fixed hydraulic orifice is defined using implicit equations.

Estimating the Parameters of a Hydraulic System   4:32

Tune parameters automatically until simulation results match measurement data. Optimization algorithms are used to obtain realistic parameter values for a hydraulic system.

Integrating Physical Systems and Controller   5:50  

Detect system integration issues in simulation. Mechanical, hydraulic, electrical, and control systems are gradually integrated into a full system model.

Logging Simulation Data   3:11  

Automatically log all simulation data from the physical system to the MATLAB workspace. No additional blocks are required to save the data.

Optimizing System Performance   6:08  

Automatically tune the performance of a hydromechanical pitch control system to meet system requirements using optimization algorithms.

Hydraulic Valve Parameters, Flow Rate   8:03  

Automatically tune hydraulic valve parameters to match flow rate characteristics on manufacturer’s data sheets using optimization algorithms.

Hydraulic Valve Parameters, Transient Response   4:57  

Automatically tune hydraulic valve parameters to match transient response characteristics on manufacturer’s data sheets using optimization algorithms.

Hydraulic Valve Parameters, Frequency Response   6:51  

Automatically tune hydraulic valve parameters to match frequency response characteristics on manufacturer’s data sheets using optimization algorithms.

Analyzing and Documenting Results   4:02  

Automatically run tests and generate a report documenting simulation results.

Using Local Solvers for Real-Time Simulation   4:22  

Configure Simscape local solvers on your physical networks to enable real-time simulation. The computations per time step are minimized while maintaining accuracy.

Simulating In Real Time: Hydromechanical Example   5:40  

Configure multiple, independent solvers to enable real-time simulation. The model of a hydromechanical pitch control system is simulated on a real-time target.

Hardware-in-the-Loop (HIL) Testing   5:21  

Use HIL testing instead of hardware prototypes to test control algorithms. A multidomain physical model is converted to C code and simulated on controller hardware.

Protecting Intellectual Property in Subsystems   4:39
