摘要:研究了非线性系统的全局跟踪问题,提出一种新的跟踪方案,寻求反馈控制律,意味着非线性系统首先必须是全局渐进稳定的,并保证在完成跟踪误差趋于0时,闭环系统的解应为有界的,则表明系统的全局渐进跟踪问题是可解的.这反映了实际问题中保证系统正常运行的条件.最后给出实例,结果表明所提方法是有效的.

关键词: 非线性系统, 全局跟踪, 反馈控制律, 全局渐进稳定

Abstract: Global tracking problems for nonlinear control systems is studied.A new tracking approach is presented.The feedback control law is found.First the nonlinear system must be global asymptotic stable and ensure that when the tracking error tends to zero,the solution of the closed-loop systems is hounded.This shows that the global asymptotic tracking problem of nonlinear systems is solvable.These have reflected the conditions that ensure of the systems normally move in the practical problems.Finally,an example is given to show that the approach is effective.

Key words: nonlinear systems, global tracking, feedback control law, global asymptotic stable
