Discrete PID Controller / Sampling times must agree

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.

Answer 1

[Arkadiy Turevskiy]

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

Answer 2

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
