An Optimal Homotopy Asymptotic Approach to a Damped Dynamical System of a Rotating Electrical Machine

Abstract:

In this paper, the non-conservative system of a rotating electrical machine is analytically investigated by means of an effective analytical approach, namely the Optimal Homotopy Asymptotic Method (OHAM). Besides analytical developments, in order to prove the efficiency and accuracy of the proposed approach, numerical simulations are performed for a specific working regime. Comparison between approximate analytical results obtained by OHAM and numerical integration results obtained by a fourth-order Runge-Kutta method emphasize that OHAM is reliable and easy to use in finding analytical solutions to damped systems.
