摘要:

研究了具有控制时滞的不确定线性分布参数系统的迭代学习控制问题,允许系统在迭代过程中初始状态值存在一定偏差。提出了基于时滞已知的P型迭代学习控制算法,给出了其L2范数收敛的充分条件,并利用Green公式、以及Gronwall-Bellman不等式等从理论上进行收敛性证明。数值例子验证了该算法的有效性。

Abstract:

Under the condition that a certain error can exist in the initial value of system state in iterative processing, an iterative learning control problem for a class of uncertain linear distributed parameter systems with control delay is discussed. A P-type iterative learning algorithm based on the known time delay is presented, and the sufficient condition of L2 norm convergence is given. The convergence of the iterative algorithm is proved by using Green formula and Gronwall-Bellman inequality. A numerical example is addressed to illustrate the effectiveness of the proposed method.
