Track Control of Uncertain Nonlinear System with Time-varying Delay
Journal Title: 河南科技大学学报（自然科学版） - Year 2017, Vol 38, Issue 2
Abstract
For the track control problem of a class of uncertain nonlinear system with time-varying delay,the extended state observer was utilized to estimate the unknown term with time-varying delay. The nonlinear tracking differentiator was used to track the derivative of virtual control in the backstepping design. Then the actual controller was derived to make the states and partial tracking signals in the closed-loop system converge to the neighborhood of the origin. The simulation results illustrate the feasibility of the approach.
