About the MPC controller's input to md

I thought I would ask you a question as I have been having some questions in creating a block diagram using MPC controller in simulink. My predecessor in my research put (target value - output from control target) plus (-1/s) into md (measurement disturbance), but I don't understand what this process is doing. If anyone can help me, I would appreciate an answer. If it is easier to understand if you provide a detailed block diagram or other information, I will provide it later. Thank you in advance for your cooperation in this matter.

Hi @Taiga,

The 'Measurement Disturbance' in the 'MPC' block are the unexpected changes affecting the system.

(Target value - Output from control target) is the error signal defining how far the output of the system is from the reference value.

The represents the integation in time domain and thus represents inegrating disturbance over the time.

The expression models the error signal with the integrated disturbance.This will help the control system to model the effect of the internal disturbances causing the error in the system.

Kindly refer to the below documentation of 'MPC Controller'

I hope this helps!
