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.

How to modify the mechanical input of a Simscape model during simulation?

I'd like to modify the physical input of my Simscape model during the simulation but I don't know how to do it. The mechanical translation block in the picture below is used to convert the rotational input into a translational movement (by mean of…

Simscape Physical Signal: Why does is exist?

What is the added value of simscape physical signals compared to normal simulink signals? As far as I can see, from a functional perspective there is no difference between the two types of signals: I can add units to both types, they both have a…

Change hydraulic block to gas block Simscape

I am creating a Simscape gas model where I need to use 3 way directional valves. Unfortunately there are no directional valves in the gas library. I used the 3 way directional valves from the hydraulic library but I get dashed red lines when I try…

(Simulink simscape)The simulation results show an unexpected high-frequency vibration in current source

Dear whom may answer of it. The schematic diagram implemented in Matlab simulink-simscape is same as Fig. 1 Then, when the electrical voltage of Vb across the inductor (Li) exceeds the forward voltage accompanied by diode forward voltage (2*Vf) and…

Can Simscape Multibody or Simscape Driveline generate automatically the dynamic equations of motion?

The description of the Simulink MATLAB package for Simscape Multibody says it can formulate the equations of motion for a mechanical system. I searched everywhere in the documentation and examples and I can't find a single example of how to do this,…

What is wrong with my Simulink model of an active suspension system?

I am new to Simulink and am trying to make a simulation of an active vehicle suspension with Simscape. For some reason, I am getting unreasonable results in my sim, despite following the examples on the mathworks website pretty closely. I have…

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…
