【摘要】 本文对美国Wisconsin大学B.A.Ogunnaike在其博士论文中提出的一种设计滞后观测器的新方法进行研究指出,Ogunnaike的滞后观测器要求被观测系统必须满足在任何控制作用下,不可测状态渐近稳定的条件。事实上,一般系统是不满足这一要求的。文章指出了Ogunnaike对滞后观测器存在的充要条件在证明过程中的错误,对该观测器提出异议。更多还原

【Abstract】 A new approach to observer design for time-delay systems which was studied in B.A. Ogunnaike’s Ph. D. thesis is given in this paper. B. A. Ogunnaike’s observer required that under any control, all unmeasurable states of observed system must be gradually stable. In fact, general systems can not meet this request. The mistakes about the proof of sufficient and necessary condition under which Ogunnaike’s observer for time-delay systems established are demonstrated. This paper indicated that Ogunnaike’s observer is not available.更多还原
