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.

Simulink: resistor with variable resistance during simulation

I´m trying to find a way to change the resistance in a resistor during simulation in simulink. I have been using the fundamental blocks in the SimPowerSystem package from Simscape and I have a functional circuit for non-variable resistors. What I…

connecting RC circuit to s-function block in Simulink

Can I connect an RC circuit from the Simscape library (as a feedback) to an s-function block and apply a time series as input? I am trying to use the Linearize tool from Control Design to obtain the frequency response of the whole system.

Matlab Simscape pressurizing and depressurizing a vessel

I am trying to do a very simple simulation in Simscape but I have the feeling I still don't fully grasp the conservative ports and physical signals. I have a very simple pneumatic model: A vessel of volume V, an air pump, a tube and a solenoid…

What do .pmdlg files mean when building simscape code libraries in Matlab

When building simscape custom code libraries matlab generates files into the sscprj folder and generates files with extensions md5, mexw64 and pmdlg for each custom code component. The mexw64 is a mex file and the md5 is for file integrity checking.…

Input/output port in Simulink

Is there a way to create an input/output port in Simulink (some workaround)? The port would be a bus and some signals are set from outside the block while some signals are set by the block. Here is an example: Given the following bus: Flow…

How can I model wings with aerodynamic properties in Simscape Multibody?

I am currently designing a Simscape Multibody model of my drone. My drone is a three-armed device, which somewhat resembles the rotors of a helicopter. The drone is supposed to rotate around itself, using a motor on each arm. Furthermore, each arm…
