Resumo(s)
The problem of controlling the level of unconsciousness measured by the Bispectral Index of the EEG
(BIS) of patients under anaesthesia, is considered. It is
assumed that the manipulated variable is the infusion rate
of the hypnotic drug propofol, while the drug remifentanil
is also administered for analgesia. Since electromyography(EMG) interferes with the BIS signal, it is considered as
an accessible disturbance. In order to tackle the high uncertain present on the system, the predictive adaptive controller
MUS MAR is used. The performance of the controller is
illustrated by means of simulation with 45 patient individual
adjusted models, which incorporate the effect of the drugs
interaction on BIS. This controller structure proved to be
robust to the EMG disturbance, changing reference values
and noise.
