I used a Discrete PID (PI) Controller block to control voltage. When I click on "Tune..." bottom I interface with this error message: message: linearization error / source: unknown / reported by: simulink control design / summery: Sampling times must agree. please help me to solve the problem.

Can you please provide youur model. Hard to say what is happening without seeing the actual model.

Hi Arkadiy Turevskiy,
I am new to controllers.So I modelled a system first, and when i tried tuning , it showed " The sample time after propagation is [0, 0]. Enter a discrete sample time in 'PI/Integrator'.
Please help. If you could send ur mail id i can send the file. Thanks in advance
