摘要
研究了一类短时延非线性网络控制系统PD型迭代学习跟踪控制问题.依据泛数理论,详细推导了当不存在初始误差时该系统对期望信号的跟踪控制过程,得到其收敛的充分条件,为网络环境下的非线性系统提供了一种新的控制策略.最后,通过示例仿真分析证实了本文所提理论的有效性,以及收敛判据的可行性.
The issue of PD-type iterative tracking control for nonlinear networked control systems(NCSs) was studied,where the network transmission was connected with short delay.By using functional analysis, a complete mathematical model was given under the condition of no initial errors.A sufficient condition for convergence was derived and the criteria of asymptotical stability for the systems were analyzed,which can provide a new methodology for the tracking control of nonlinear NCSs.The efficacy and feasibility of the proposed methods was shown by presenting simulation results from a nonlinear NCSs example.
