In most of the industrial processes, there are multi-rate(MR) systems that includes more than one sample rate. Also, when these systems are controlled by model predictive control which is useful to control of constrained multivariable process, model mismatch can occur if process dynamics change and a new model should be identified in closed-loop when the process need to comply particular operating, meeting product specification or safety requirement. In this research, the re-identification problem of general dual-rates system in a closed-loop with a MPC controller is addressed, considering the lifted system and known dynamic characteristics. In comparison with the existing approach, the proposed identification method provides more accurate and realistic model. |
