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。
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.
