Simscape™ provides an environment for modeling and simulating physical systems spanning mechanical, electrical, hydraulic, and other physical domains.

Simscape™ provides an environment for modeling and simulating physical systems spanning mechanical, electrical, hydraulic, and other physical domains.

Simscape models can be used to develop control systems and test system-level performance. We can extend the libraries using the MATLAB® based Simscape language, which enables text-based authoring of physical modeling components, domains, and libraries.

Correct way to use switch and voltage sensor in Simulink Simscape

I am trying to use a switch in Simulink Simscape. I want to see what voltage appears on both sides of the switch. The switch should close when the applied physical signal is greater than the threshold of the switch. It should be open otherwise. …

How to model a current source with a prescribed waveform in Simscape?

I know the Simscape current source block, but this one can only model a current source with DC, AC and noise components. Instead of an AC current, I would like to model a current wave that is defined based on a general current vector in time. Is…
