REC650 1MRK008514-AA Predictive Controller

REC650 1MRK008514-AA Unlike conventional PID control, non-parametric model-based predictive control algorithms use a rolling optimisation strategy to calculate the current controller output by predicting the state of the future output of the system through a predictive model. Depending on the implementation, there are various algorithms, e.g., internal mode control, model algorithm control, dynamic matrix control, etc.

REC650 1MRK008514-AA Practical predictive control algorithms have been introduced into DCSs, e.g., the IDCOM control algorithm package has been widely used in real industrial processes such as hydrocracking, catalytic cracking, atmospheric distillation, and naphtha catalytic reforming.

REC650 1MRK008514-AA predictive controllers do not simply place the Kalman filter before the previous predictive control for noise filtering, but rather the Kalman filter is used as an optimal state speculator, performing both optimal state speculation and noise filtering.
