针对一类带有强漂移项的高阶非完整系统,基于后推设计方法,input-state-scaling变换技巧和模糊系统的逼近能力提出了一种新的自适应控制方案。该方案保证闭环系统的所有信号最终一致有界,且系统的状态收敛到零的一个小邻域内。
In this paper, a new design scheme of robust adaptive fuzzy control is presented for a class of uncertain high-order nonholonomic systems with strong nonlinear drifts. The design is based on backstepping, input-state-scaling techinique and the approximation capability of fuzzy systems. Uniform ultimate boundedness of all the signals in the closed-loop are guaranteed, and the system states are proven to converge to a small, neighborhood of zero.
