Modeling Multidomain Physical Systems

With Simscape you build a model of a system just as you would assemble a physical system. Simscape employs a physical network approach to model building: components (blocks) corresponding to physical elements such as pumps, motors, and op-amps, are joined by lines corresponding to the physical connections that transmit power. This approach lets you describe the physical structure of a system rather than the underlying mathematics. From your model, which closely resembles a schematic, Simscape automatically constructs equations that characterize the behavior of the system. These equations are integrated with the rest of the Simulink model.

Simscape libraries provide more than 24 electrical elements, 15 hydraulic elements, and 23 mechanical elements that can be connected with one another. These basic elements can be combined to create more sophisticated components.

You can use the sensor blocks in Simscape to measure values for mechanical (force/torque, velocity), hydraulic (pressure, flow rate), or electrical (voltage, current) variables, and then pass these signals into standard Simulink blocks. Source blocks enable Simulink signals to assign values to any of these variables. Sensor and source blocks let you develop an entire control algorithm in Simulink and connect it with a Simscape network.
