| Tittel: | Modified Smith-predictor multirate control utilizing secondary process measurements |
| Forfattere: | Ergon, Rolf |
| Dato: | 2001 |
| Sammendrag: | The Smith-predictor is a well-known control structure for industrial time delay
systems, where the basic idea is to estimate the nondelayed process output by use of a
process model, and to use this estimate in an inner feedback control loop combined with an
outer feedback loop based on the delayed estimation error. The model used may be either
mechanistic or identified from recorded data. The paper discusses improvements of the
Smith-predictor for systems where additional secondary process measurements without
time delay are available as a basis for the estimation. The estimator may then be identified
from recorded data also in the common case when the primary outputs are sampled at a
lower rate than the secondary outputs. A simulation example demonstrates the feasibility
and advantages of the suggested control structure. |
