Design of Cross-directional Controllers with Optimal Steady State Performance
نویسندگان
چکیده
Actuator constraint handling is necessary for many crossdirectional controllers. We discuss how optimal steady state performance can be guaranteed by modifying an internal model control structure with a non-linear element. For the simple dynamics associated with most web processes this also gives good closed-loop dynamic behaviour. Thus unconstrained control design techniques may be applied directly to the constrained control problem.

Robust cross-directional control of paper making machines with saturating actuators
In this report we discuss the design of cross-directional controllers which are guaranteed to be robustly stabilizing while incorporating a quadratic programme for steady state performance. The report is loosely based on the technical report of Akkermans (2003) who proposes using the multivariable circle criterion to guarantee closed-loop stability of cross-directional controllers in the presen...
متن کاملAnalysis of steady-state performance for cross-directional control - Control Theory and Applications, IEE Proceedings-
The authors analyse the steady-state behaviour of a class of cross-directional controllers that are pertinent to general web-forming processes. Their analysis is framed in terms of the controllable space prescribed by the interaction matrix and general discrete orthonormal basis descriptions of both the input and output space under the assumption of closed-loop stability. The specific choice of...
