摘要

The problem of state estimation for microalgae growth processes in batch cultures based on an extended Droop model is addressed. Sufficient conditions for local strong observability are derived within an unknown input framework considering a biased optical density (OD) measurement and a (non-biased) substrate measurement. To account for discrete-time measurements with different sampling rates a continuous-discrete extended Kalman Filter is designed and tested as well as within numerical simulations as also with experimental data for Haematococcus pluvialis.
