Abstract:
To control non-linear systems along the whole range of operations, Non-linear control
techniques are used. Neural network and generalized minimum variance controllers are
two of the most common non-linear control techniques.
In this paper, Local optimal controller is generalized to deal with non-linear systems.
This new non-linear controller is used to deal with multivariable systems as well as
single-input single-output systems.
The effectiveness of the non-linear local optimal controller when dealing with
multivariable systems is represented in this paper based on the results obtained from the
high purity distillation column model.
