Existing large industrial control systems often exhibit poor tracking and disturbance rejection capabilities due to a large number of decentralized control loops. To improve these, a stabilizer design procedure is proposed based on H∞ optimization. The procedure is simple to apply and requires only some of the closed-looptransfer functions. Application of the approach in the Syncrude utility plant shows that it can indeed improve the disturbance rejection performance and the stabilizer designed is easy to implement and test in practice.
