PID Controller block, which can cause PID Tuner to give a different response from
the simulation.- Your Simulink model has strong nonlinearities in the plant that make the linearization
invalid over the full operating range of the simulation. - You selected an operating point using PID Tuner that is different from the operating
point saved in the model. In this case, PID Tuner has designed a controller for a
different operating point than the operating point that begins the simulation. Simulate
your model using the PID Tuner operating point by initializing your Simulink model
with this operating point. See “Simulate Simulink Model at Specific Operating Point”
on page 1-119.
