Utilities

Required and commonly used blocks for setting simulation environment, interfacing with Simulink^® models, and generating custom components on-the-fly

This library contains required and commonly used blocks for setting simulation environment, interfacing with Simulink models, and generating custom components on-the-fly.

The blocks in the Network Couplers library provide you with starting points for splitting your Simscape™ network into separate smaller networks interfaced to each other through Simulink connections.

Configuring an EV Simulation for Multirate HIL

An electric vehicle model suitable for multirate Hardware-In-the-Loop (HIL) deployment. The example uses the Simscape™ Network Couplers Library to split the model into separate Simulink® subsystems that can be deployed at different sample rates. This allows you to run parts of the system (for example thermal components) with a slower sample time thereby reducing overall computational cost.
