：为了准确地获得信号中谐波、间谐波成分的频率和幅值等参数， 提出了一种新的检测算法，即E S P R I T( E s t i m a t i o n o f s i g n a l P a r a m e t e r s v i a R o t a t i o n a l I n v a r i a n c e T e c h n i q u e s ) 。此算法是一种基于子空间技术的高分辨率检测方法，它把 信号分解为信号子空间和噪声子空间，能够精确地估计出被噪声污染的正弦信号的频率，幅值等
Embedded Control：From Asynchrony to Synchrony and Back We propose in this paper a historical perspective of programming issues found in the implementation of control systems, based on the author’s observations for more than fifteen years, but especi
