I have two PI controller running in parallel both controls the same output variable, based predefined input conditions I would like to transfer control from Control A to Control B without any variation in the output response. would be great to get any suggestion on efficient way of doing it.
Using Matlab Simulink as implementation plattform
Thanks

Dear Sreeraj Arole
I have illustrated my idea for your problem, attached as an image to this comment.
In the image, t1, t2, t3, and t4, are discretionary, and you can set them to optional values. Even you may change the time signal to any shape you prefer, square wave, saw-toothed, sine wave, several pulses, with respect to your control-selector strategy. But beware that, the times of transfer from control A to control B, should not over-lap, because the control signal then becomes multiple-valued and hence you may encounter an error in Simulink simulation. You can as well modify the amplitude of the pulse, by multiplying it to a constant gain, or even multiplying it by a time-varying function described as another time-signal.
Your control-selector could be utilized to program t1, t2, t3, and t4.
Thank you Ahmed Abougarair I am afraid since the model is tightly associated with the plant model and other part sharing the model will be difficult.
