Abstract

Abstract: This paper uses subharmonic Melnikov method to analyze and calculate the oscillating periodic orbits and rotating periodic orbits of a dual-unit power system. Meanwhile, the paper presents a control scheme of power system by sliding mode for a problem of tracking control which realizes that the power system can track any known smooth signal. The numerical simulation results demonstrate the feasibility of sliding control technology, and the correctness of the discussion.

Key words: dual-unit power system, Melnikov method, subharmonic periodic orbits, chaos
