A Characteristics Approach to Parameter Identification in Distributed Systems
Frank J. Evans · 1969
a not.iceable minimum of aZe(~) occurs at T = TI for positive values of T a not.iceable maximum of %e(T) for negative values of r occurs at. T = -Ti. Figs. 2 and 3 shoF the variation of -aZe(7) obtained for a range of T from -1.5T1 to 1.57'1 and for t.wo values of TP (i.e., 0.9T1 and 1.17'1). These results suggest that,, by direct visualization of the correlation function as an oscillogram, sufficient. information should be obtained to achieve satisfactory adjust- ment of t.he cont,roller delay time. Abstract-A method is proposed for identifying linear distributed parameter systems from measurements on the system and inputs. Based on characteristics, the method is direct and converges rapidly for the class of problems discussed.
