Bjarne ------------------- AUTOMATIC CONTROL: an enabling technology for the process industry The contributions that automatic control can make to both mechatronic and processing systems are assessed and compared. For the former, the objective= is to enable system integration, while the latter often require enhancement of system productivity. The industrial processing environment is briefly discussed. Industrial processes require constantly-improved operation in terms of both productivity and ecology. Better designs help, but do not suffice to meet the high expectations. Processes have to run optimally despite the inevitable disturbances and lack of= process knowledge. A few optimization strategies are presented and compared. Simulation and experimental results obtained with a biofilter and a semi-batch laboratory-scale reactor are presented.
