| Abstract: | A computational system for finite Fourier sequence is established with the thought of symbolic computation. Large quantities of manual calculations can be avoided when it is applied to the problems involving harmonic balance method. It is used to compute limit cycles by perturbation incremental method and a fine result is shown. |
