Simscape Model and simulate multidomain physical systems Simscape™ provides an environment for modeling and simulating physical systems spanning mechanical, electrical, hydraulic, and other physical domains. It provides fundamental building blocks from these domains that you can assemble into models of physical components, such as electric motors, inverting op-amps, hydraulic valves, and ratchet mechanisms. Because Simscape components use physical connections, your models match the structure of the system you are developing. Simscape models can be used to develop control systems and test system-level performance. You can extend the libraries using the MATLAB® based Simscape language, which enables text-based authoring of physical modeling components, domains, and libraries. You can parameterize your models using MATLAB variables and expressions, and design control systems for your physical system in Simulink®. To deploy your models to other simulation environments, including hardware-in-the-loop (HIL) systems, Simscape supports C-code generation. Learn more about physical modeling. Key Features ▪ Single environment for modeling and simulating mechanical, electrical, hydraulic, thermal, and other multidomain physical systems ▪ Libraries of physical modeling blocks and mathematical elements for developing custom components ▪ MATLAB based Simscape language, enabling text-based authoring of physical modeling components, domains, and libraries ▪ Physical units for parameters and variables, with all unit conversions handled automatically ▪ Ability to simulate models that include blocks from related physical modeling products without purchasing those products ▪ Support for C-code generation Modeling a DC Motor 6:31 Model a DC motor using electrical and mechanical physical modeling components. Simscape 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.

Cross-section illustration of an electrohydraulic servo-valve that uses a flapper-nozzle amplifier, highlighted in yellow (right). The colored blocks in the associated Simscape model (left) correspond to the colored arrows, which represent typical hydraulic flow paths. Physical System Modeling With Simscape, you build a model of a system just as you would assemble a physical system. Simscape employs a physical network approach, also referred to as acausal modeling, to model building: Components (blocks) corresponding to physical elements, such as pumps, motors, and op-amps, are joined by...

Modeling a DC Motor 6:31 Model a DC motor using electrical and mechanical physical modeling components. Modeling Hydraulic Components Simscape provides hydraulic building blocks that model fundamental hydraulic effects and can be combined to create more complex hydraulic components. These blocks define the pressure/flow relationship for basic physical effects, such as fluid compressibility, fluid inertia, mechanical friction, energy transduction, and flow through basic fixed and variable orifices. You can define a fluid by entering its fluid properties. More elaborate hydraulic components...

Running Parameter Sweeps: Fan Speed 4:38 Run a parameter sweep using a standalone executable. Convert the Simscape™ model to C code to enable rapid testing of parameter values. Configuring your models to run in real time enables you to use hardware-in-the-loop testing instead of expensive prototypes to test your system. You can find mistakes earlier in the development process, reducing costs and shortening the design cycle. Use HIL testing instead of hardware prototypes to test control algorithms. Convert physical model to C code and simulate in real time on controller hardware. MATLAB and...
