Steady-state analysis of a periodically excited nonlinear system

An algorithm is proposed to calculate the steady-state response of a strongly nonlinear system under periodic excitation. The method combines a Volterra approach based on the algorithm developed by L.Q. Chua and C.-Y. Ng, (see Electron. Circuits Syst., p.257-69, 1979) with some concepts adopted from the well-known harmonic balance technique. The resulting method eliminates the major shortcomings from both techniques while is preserves the major advantages of each. To demonstrate the possibilities of this new algorithm, some examples are provided
