im trying to run a simulink model of pi controller through a m-file in a repetitive way.in each iteration a value of the pi parameter will be set,and the corresponding output will aslo be tabulated.in the next iteration the pi parameter will also be changed by a new values.how this can be done?

actually the overshoot,setling time,error etc. will be determined for a given set of value of pi parameter.

in the next iteration new value of pi will be set,again for those new set of values, settling time,overshoot,error will be calculated.

its for optimization.

the previous value of pi are not needed,only the settling time,overshoot,steady state error,etc.are required to be returned.when minimum output(error,over shoot,etc) will be found iteration will be stooped.that value of pi will be saved permanently

I am not clear what exactly you want to do.

You can stop the simulation from m-file, change your parameter (pi) and start the simulation again.

To start the simulation, use

set_param(gcs,'SimulationCommand','start');

To pause the simulation, use

set_param(gcs,'SimulationCommand','pause');

To resume the simulation, use

set_param(gcs,'SimulationCommand','continue');

and To stop the simulation, use

set_param(gcs,'SimulationCommand','stop');

yes its numerical value.

pi controller is available in simulink.its a musked inbuild block.doubble clicking on it, opens a dialog box,to change the parameter.how i would use a constant bolck.
