Simulink Stateflow: Wait for Parallel States

I would like to create a state machine in Stateflow that enters into multiple parallel states (A&B&C) and then exits to an end state (D) only when a condition from each parallel state has been achieved. The picture demonstrated below exits when…

How to charge a battery model by sun irradiance model?

I am new at modeling. I created a mathematical model via some equations to calculate sun irradiance. The last function does it but I couldn't connect the output (pin) to the battery to charge. What should I do ? Heard just that I needed to add a…

How to set parameters in Scilab blocks from SciPad?

I don't know if anyone faced the same problem! In MATLAB, we can easily set the parameters of Simulink blocks from m-files. For example, we can change the coefficients of transfer functions, PID gains, step-input magnitude, simulation time, etc. In…

How to use structure as parmeter for simulink subsystem and use fields inside as block parameters?

I have created a subsystem in Simulink. I would like this subsystem to have a single parameter, which is supposed to be a Matlab structure. Inside the subsystem, I would then like parameters of some of the blocks to be the fields of this…

How to offset a time value in Simulink?

I've been trying to calc dy/dt= 2y/t, y(1)=1 on Simulink. I adjusted the IC=1 on the integrator but of no avail as it keeps throwing me an error "divisibilty by 0" . I just need to offset t=0 in the equation and run from t>0. How do I? My model

I modelled the sun in R, but can't do the same in Simulink

I'm very new in modeling systems. With a friend's help, We created this model in R hours <- seq(6+20/60, 18+31/60, 0.01) h_radians <- (pi/12) * (hours - (12+26/60)) doy <- 268 decl_radians <- 23.45 * sin(2*pi*(284+doy)/365) * pi /…

Flip sign of fixed point signal without using gain block Simulink

I have an incoming signal and I want to change it's sign. I can easily add a gain block (=-1) and flip the sign or multiply the signal by -1. However, I want to avoid this because the incoming signal is fixdt(1,24,39) which is very small.…

Matlab Simulink file run time in hours: Relation between step size and simulation/stop time

I intend to run a Matlab Simulink model (of 400 ODEs i.e. 400 ODE models) with a fixed step size of 200e-06 and a simulation/stop time of 52 hours. As per my understanding, the Simulink stop time unit is in seconds. Does it mean that I need to run…

multiple triggered subsystem + algebraic loop, initialisation problem

I have a Simulink diagram which contains multiple triggered subsystem with different timestamp. In this model I also got a feedback loop inducing an algebraic loop. Therefore the signal must be initialised, in order to do that, I used a Memory…
