摘要: 针对含不可测外扰的非最小相位对象,发展了一种不要求"持续激励"和"严格正实"条件 的自适应控制系统.提出了这类系统的在线算法并证明了它的收敛性.所提出的算法保证 了自适应系统的稳定性和足够小的控制误差.Abstract: In this paper, an adaptive control system without "persistent excitation" and "strictly positive real" conditions is developed for non-minimum phase plant disturbed by unmeasurable disturbance. An on-line algorithm for the system is presented and its convergence is proved. Using the algorithm the adaptive system is stable and the control error is small enough.
