| 摘 要： | 研究了一类存在建模误差时的鲁棒自校正问题.在对象的模型误差是“相对小”的情况下,提出了具有辨识误差死区的辨识算法和相应的控制律;通过理论分析,给出厂辨识算法的收敛性;在给出的极点配置自校正定理中证明了对存在任意建模误差及任意有界初始状态的被控对象,整个自适应系统中所有的信号保持有界,因而也就表明所提出的控制算法对模型误差有很强的鲁棒性.

| Abstract: | A new pole assignment adaptive control algorithm has been developed. For a relatively small model error, an identification algorithm for the dead zone and the corresponding control rules are proposed. In the algorithm, feedforward and feedback polynomials have also been introduced so that "bursting" can be avoided in practice. It is proved that, when there exist an arbitrary modelling error and the bounded initial state, all the signals in the adaptive system remain bounded for any controlled object. |
