FREQUENCY-DOMAIN STABILITY ANALYSIS OF ASYNCHRONOUS LEARNING CONTROL SYSTEM

he frequencydomain stahility of general asynchronous learning control system(ALC)is an alyzed, its modification with more strong stability condition,based on memory with forgetting factor andfeedback from E_(k+1)(s), is derived, the strict proof on related theorem and corollary is provided, and the geometric relationship between the learning matrix and the stability circle is discussed. Furthermore,an asymp-totic stability condition of ALC is obtained by using DNA method and some conclusions are given.
