| 中文摘要 |
| 迭代学习控制方法应用于网络控制系统时, 由于通信网络的约束导致数据包丢失现象经常发生. 针对存在输出测量数据丢失的一类非线性系统, 研究P型迭代学习控制算法的收敛性问题. 将数据丢失描述为一个概率已知的随机伯努利过程, 在此基础上给出P型迭代学习控制算法的收敛条件, 理论上证明了算法的收敛性, 并通过仿真验证理论结果. 研究表明, 当非线性系统存在输出测量数据丢失时, 迭代学习控制算法仍然可以保证跟踪误差的收敛性. |
| 英文摘要 |
| This paper analyzes the stability of the iterative learning control (ILC) applied to a class of nonlinear discretetime systems with output measurement data dropouts. It is assumed that an ILC scheme is implemented via a networked control loop for the nonlinear system and that the packet dropout occurs due to limitations in network communication. The data dropout is described as a stochastic Bernoulli process with a given probability; on this basis we derive the convergence condition for the P-type ILC algorithm. The theoretical analysis is supported by the simulation of a numerical example; the convergence of ILC can be guaranteed when some output measurements are missing. |
