Abstract: |
In this paper, we
demonstrate continuous-time adaptive control for nonlinear system of two
funnel tanks in series. For this purpose continuous-time input-output linear model
is considered describing nonlinear system in the neighborhood of an operating
point. The two approaches discussed here are direct estimation and alternate
delta model. In the case of direct approach the key lies in the differential
filters used to compute estimates. In the second strategy parameters of
corresponding delta model are recursively estimated. A feedback control configuration
with to degrees of freedom is adopted. In order to guarantee stability as
well as asymptotic tracking of the step reference and step load disturbance attenuation,
polynomial method is taken into account for the resulting controllers. A
simulation software tool implementing illustrative model of two funnel liquid
tanks in series has been studied in detail. |
