| Abstract: | Using lifting technology, this paper extends the state--space DMC algorithm to a practical case of multirate systems with fast input control and slow output sampling. Performance of such a dual--rate DMC algorithm is eampared with that of single--rate systems and the reason for its advantages is established. Simulation results verify that this dual rate predictive control algorithm can follow setpoints without overstrikes, and quicker system response can be abtained. |
