Hard to answer without having more details. Can you attach your model. Also, what version of MATLAB are you using, please do

>>ver

to check.

i want to use discreate pid controller for closed loop speed control of bldc motor. I simulated for open loop with sample time as 1e-6. in case of closed loop, when i presed the tune button i am getting an error: Linerization error(message),unknown(source),simulink control design(reported by),sampling times must agree(summary). Help me how to overcome this error?plz.

I am using matlab R2013a. i have attached the file with this mail
