Second Order Step by Step Sliding mode Observer for Fault Estimation in a Class of Nonlinear Fractional Order Systems

Seyed Mohammad Moein Mousavi, Amin Ramezani

摘要:

本文研究了分数阶非线性系统的观测器形式的故障估计问题。为此,一步一步的二阶滑模观测器。利用分数阶不等式分析了观测器估计误差的稳定性,并给出了保证估计误差有限时间收敛的条件。最后,通过数值算例验证了该观测器的有效性.

英文摘要:

This paper considers fault estimation in nonlinear fractional order systems in observer form. For this aim, a step by step second order sliding mode observer is used. By means of a fractional inequality, the stability of the observer estimation errors is analyzed and some conditions are introduced to guarantee finite time convergence of estimation errors. Finally, in a numerical example, effectiveness of this observer is demonstrated.
