Performance Monitoring, Tuning and Diagnosis of DMC under Stochastic Disturbance

This study focuses on the performance monitoring, diagnosis and tuning of DMC systems with stochastic disturbance. A DMC performance benchmark curve is defined and estimated from the routine process data. The characters of the benchmark curve are discussed and based on which a procedure for monitoring, diagnosis and tuning of DMC is designed. The utility of this procedure is confirmed by simulations.
