摘要
针对一类非线性微分代数系统,提出系统渐近输出跟踪的概念.利用M导数方法及系统的M向量相对阶,分析了此类系统的渐近输出跟踪,得到了此类系统可实现渐近输出跟踪的条件.对一组确定的参考输出给出了反馈控制律,使对应的闭环系统有确定的不含脉冲的解,并实现了系统的输出渐近跟踪确定的参考输出.通过算例证明了所给出方法的正确性与可行性.
The concept of asymptotic output tracking was proposed for a class of nonlinear differential algebraic systems. The asymptotic output tracking for the differential algebraic systems was analyzed using M-derivative and M-vector relative degree. The conditions for the systems to realize the asymptotic output tracking were obtained. For a given reference output signal,the feedback control law was constructed,where the corresponding closed loop system has the unique impulse-free solution and the reference output determined by the asymptotic output tracking is realized. The correctness and feasibility of the proposed method has been proved through the calculation example.
