Please Solve My Problem in Integration(Embedded MATLAB Block)

function p= fcn(x)

p=int (x)

this is my program in embedded block

here,

x=step input to embedded block; p=output from embedded block to plot

I have error in these steps please help me and assist me to rectify this error

Which int function are you using/intending to use?

• int from the Fixed-Point Toolbox
• int from the Filter Design Toolbox
• int from the Symbolic Math Toolbox

I am going to assume that you want to integrate your input signal with respect to time. If that's the case, then you don't need an Embedded MATLAB Function block, use an Integrator block instead, that's what it's there for.

If I misunderstood your question, please clarify and provide the error message that you're getting.

HTH,

Thanks for your answer.

Actually, I designed my mathematical model using MATLAB/SIMULINK it is for some control purpose in my project. During feedback when using two "INTEGRATOR BLOCK" in my model i've error "at some time integrator output become infinity or NAN" i tried by applying limits it causes the constant output (i.e., lower limit output from one integrator and upper limit output from another integrator)from integrator. Because of this i get constant error output form two integrator.

It sounds like your integrators are saturating. You need to figure out what's causing them to saturate and fix the root cause. Using Embedded MATLAB block is not going to help. Use scopes to look at the various signals around your feedback to try and figure out where the error is.
