摘　　要：针对一类具有奇数次幂积分链的高阶非线性系统,通过构造恰当的Lyapunov函数,找到了能够保证其渐进跟踪一个光滑动态参考信号的采样控制器.仿真实验表明,当采样周期较大时,所设计的控制器比Emulation控制器具有更好的控制性能.By constructing an appropriate Lyapunov function,a novel sampled-data controller is proposed for a class of high-order nonlinear systems with odd integral chains to ensure that the resulting system can asymptotically track a smooth dynamic reference signal.The simulation results show that compared with the emulation controller the proposed control scheme has better control performance when the sampling period is large.
