| Summary: | Plant parameter variations due to environmental changes present a
problem in any control system design. In this paper, two adaptive control
techniques which compensate for large or small parameter variations are
proposed. The variations in the parameters are identified by using the
error between the plant output and a fixed model output together with
the plant sensitivity functions which are used to identify plant parameter
variations. One adaptive technique uses the identified parameter
value to physically change the plant parameter and the other adaptive
technique uses the identified parameter value to generate a compensating
input to the plant. A mathematical model for the simultaneous
generation of the desired output and the sensitivity functions is
described. Several examples using both techniques are considered. |
