Haar wavelet method for solving lumped and distributed-parameter systems
C.F. Chen, Chun‐Hui Hsiao · IEE Proceedings - Control Theory and Applications · 1997
An operational matrix of integration based on Haar wavelets is established, and a procedure for applying the matrix to analyse lumped and distributed-parameters dynamic systems is formulated. The technique can be interpreted from the incremental and multiresolution viewpoint. Crude as well as accurate solutions can be obtained by changing the parameter m; in the mean time, the main features of the solution are preserved. Several nontrivial examples are included for demonstrating the fast, flexible and convenient capabilities of the new method.
