How do I incorporate a feedforward control signal into an MPC block?
I have designed a feedback control system using an Model Predictive Controller block for a DC Motor servomechanism. In order to reduce the steady-state error I want to include a feedforward control signal that I can estimate and predict. The MPC block therefore needs to have knowledge of the feedforward control signal as, I assume, a measured disturbance which is able to be previewed. I have implemented this as below:
I haven’t been able to improve the controller performance with this architecture as I would expect (previous PI + Feedforward works very well), so I wanted to ask whether this was the correct approach to include the feedforward signal into the MPC block?I have designed a feedback control system using an Model Predictive Controller block for a DC Motor servomechanism.
