What is Simulink: Definition and 115 Discussions

Simulink is a MATLAB-based graphical programming environment for modeling, simulating and analyzing multidomain dynamical systems. Its primary interface is a graphical block diagramming tool and a customizable set of block libraries. It offers tight integration with the rest of the MATLAB environment and can either drive MATLAB or be scripted from it. Simulink is widely used in automatic control and digital signal processing for multidomain simulation and model-based design.

    MATLAB Analyzing Graphs with Simulink and Laplace Transforms

    the question goes like this: the first part asks to utilize simulink to obtain the graph pattern: the second part requires us to make use of laplace transform and inverse laplace transform to solve the initial value problem: the third part asks us to compare both the results...

    Simulink: Understanding Time Steps and Sampling Frequencies

    Hi, I have a project due that has to be done in Simulink. I am somewhat familiar with Simulink, but some things don't make sense to me. First off, What determines the time step between each iteration? eg. when you have a clock in the model, what determines the change in time from one...

    Set off differential Equations in Simulink

    hi, I have a problem where i am trying to model a change in X (biomass) over time, its a growth of biomass over time. I have three equations that are linked The first for Biomass is dX/dt = [0.25*S/(0.005 + S)]X - (X/V)*dv/dt Where dv/dt = 529.68*EXP(0.177t) and ds/dt =...

    Simulink Help (i would imagine its a pretty simple solution)

    I have a system, setup to simulate the braking of a vehicle. the vehicle decelerates from 400 mph to zero using a parachute, and conventional brakes the parachute deploys at 400mph to prevent the brakes from overheating they need to be used at a lower velocity at present i have a...

    Simulink: Strange problem with disappearing objects in VR Sink

    I have a few simulink models that I've made over the years, but the computers at this one particular computer lab have a weird response to them. When I try to view the VR model on simulink, it's as if most of the object is clipped out of view unless I get extremely close to it. I see mostly...

    The integration block in simulink

    Hi every body, I am not sure if this question is suitable in this box, so I will have a try. I just started to study Matlab and Simulink. There's one thing i do not understand: Why does the integration block in simulink have the symbol 1/s. Does it have something linked with laplace...

    SIMULINK Help: Forces Acting on a Body

    Hello everyone... I have a little question on simulink. When forces acting on a certain body are given (just like a spring-damped system for example) can we automatically implement such a model in simulink by only using the equations of motion (mä = sum of given forces) or do I always need...
