document: The BIOGENES system for knowledge-based bioprocess control The application of knowledge-based control systems in the area of biotechnological processes has become increasingly popular over the past decade . This paper outlines the structure of the advanced knowledge-based part of the BIOGENES Copyright control system for the control of bioprocesses such as the fed-batch Saccharomyces cerevisiae cultivation . First , a brief overview of all the tasks implemented in the knowledge-based level including process data classification , qualitative process state identification and supervisory process control is given . The procedures performing the on-line identification of metabolic states and supervisory process control -LRB- setpoint calculation and control strategy selection -RRB- are described in more detail . Finally , the performance of the system is discussed using results obtained from a number of experimental cultivation runs in a laboratory unit
