I am having a similar problem to this thread (<http://www.mathworks.com/matlabcentral/answers/41582-control-a-simulink-module-by-an-m-file>) in which I would like to alter the resistance of my circuit during simulation. I have tried most of the methods suggested in it but to no avail, I am not entirely sure how to implement the clock/function method. Do I require an output to the function, and do I need to call the function within my main m-file? This is what I have written so far:
function Rchange(time) %#codegen coder.extrinsic('set_param'); if time > 20 set_param('autotest\R1','Resistance','1350'); elseif time > 40 set_param('autotest\R1','Resistance','750'); end
Also, I am unable to use the variable resistor which would seem like the most logical solution to my problem as I am running SimPowerSystems and do not know how to convert signals using the s-ps converters and reconnecting it back to my circuit.
Any help will be appreciated.
