控制非线性系统仿射采样反馈镇定的充分Lie代数条件

Sufficient Lie Algebraic Conditions for Sampled-Data Feedback Stabilizability of Affine in the Control Nonlinear Systems

John Tsinias, Dionysis Theodosis

摘要:

对于一般的非线性自治系统,通过时变采样数据反馈,建立了半全局渐近稳定的可能性的李雅普诺夫特征。利用这一结果,我们得到了具有非零漂移项的控制非线性系统的仿射采样反馈半全局镇定的李代数充分条件。相应的命题构成了反馈镇定的“Artstein-Sontag”定理的推广。

英文摘要:

For general nonlinear autonomous systems, a Lyapunov characterization for the possibility of semi-global asymptotic stabilizability by means of a time-varying sampled-data feedback is established. We exploit this result in order to derive a Lie algebraic sufficient condition for sampled-data feedback semi-global stabilizability of affine in the control nonlinear systems with non-zero drift terms. The corresponding proposition constitutes an extension of the "Artstein-Sontag" theorem on feedback stabilization.
