A DYNAMICAL SUPERVISOR STRATEGY FOR MULTIPRODUCT PROCESSES

Competing in the global marketing place puts additional burden on mult i-product manufacturing processes. Each transition to a different prod uct grade must be made efficiently with the simultaneous objectives of minimal off-spec product and feed stock waste, and non-violation of s afety and environmental constraints. In this work, a hybrid, dynamical supervisory control strategy is presented to address transition contr ol of multi-product processes. The scheme involves the selection of th e best setpoint controller, from an existing family of feedback contro llers so as to cause the output to track the desired setpoint. The per formance of the supervisory control strategy is demonstrated on an exo thermic reactor.
