摘要：AbstractThis paper proposes a systematic methodology able to analyze the stability and estimate the domain of attraction of output regulated systems with rational nonlinearities. The fundamental idea is to represent the system’s equations in the differential-algebraic form and subsequently address the stability problem by semidefinite optimization. The analysis of a nonlinear plant with sinusoidal output tracking control is provided to numerically exemplify our proposed method.
