Changing equations permanently
Changing equations permanently
Feb-16-13 02:42:03
I have a problem that should be easy but I could not solve.
I want to write a block that receives x as input and creates y.
It should be:
y =0 up to when x > xMax for the first time
and:
y=1 after that.
It should be y=1 even if later x is back below xMax.
Someone can help?

Code:
model M
Real x,y(start = 0.0);
parameter Real xMax = 0.5;
equation
der(x) = sin(time);
when x > xMax then
y = 1.0;
end when;
end M;

Thanks.
It is easy and effective.
The when clause indeed opens to me a new world of options and possibilities.
