Abstract: The principle of soft-sensing technique from advanced control system in industrial process was introduced. Soft-sensing model establishment,correction and application were discussed. In order to measure important parameters of fer-mentation process,fsuch as matrix concentration,biomass concentration and production concentration, the various meth-ods of soft-sensing were studied.
