Rolf Ergon, Professor Emeritus, Ph.D.
Research interests:
- System identification and chemometrics/multivariate calibration
- Dynamic system multivariate calibration, e.g. product quality estimation
based on information carried by known process inputs and secondary process
measurements.
- Process monitoring and control based on product quality estimation.
