Hi, I'm having some troubles in creating ssc file where I need to use while loop (or maybe for). Here is my code:
parameters
gain = { [0 0 1/3], '1' }; % Gain
max={[0.3 0.1 0.25],'1'} %Maximum pressures
end
parameters
stop = { 0, '1' };
k={1,'1'};
end
equations
while stop<1
if I<=sum(max(1:k))
stop=1;
coef=gain(k);
end
k=k+1;
end
O == coef * I;
end
And when I try to build library with ssc_build I get message like this:
Illegal flow control construct 'while' in equation block
Am I doing something wrong, or there is no possibility in simscape language to use "while" and "for" statements (although conditional "if" is allowed)?
Thanks in advance.

while and for loops are not allowed in the Simscape language, see the equations documentation ("Supported Functions" section) and Defining Component Equations in the Simscape documentation. What are you trying to do?

I would suggest doing this in Simulink/Stateflow or Embedded MATLAB and using a Simulink->PS Converter block to feed to the flow rate sources. Alternatively, if you want to stay within the Simscape environment, you could probably use the PS Switch block in conjunction with the PS Max and PS Min blocks.

Hi Arnaud,
while and for would be helpful, to create parameter-driven discretisations of simscape-blocks (like in Modelica language) for any type of lumped models.

I agree, Simscape not supporting while and for loops is pretty big limitation
