Kurzfassung englisch:
The paper presents the implementation of a model based
predictive control algorithm of an industrial drying process for
Viscose staple fibres. A short review of the earlier published
modelling procedure presents the linearised multi-input multioutput
(MIMO) state space formulation of the design model.
The design of the predictive control scheme incorporates constraints
on the manipulated variables, set-points for the manipulated
variables, and active disturbance rejection for the main
disturbance variables of the drying process. Some simulation results
demonstrate the beneficial effects of this structure, and the
choice of proper weightings is also briefly discussed. Implementation
issues and various measured results are presented. The
problem of redundant but biased measurements of fibre humidity
is addressed and the superior performance of the new concept
compared to the existing PID-control is demonstrated. Both energy
consumption and variation of humidity in the final product
are significantly reduced by the successful implementation.
