On the Intersection Problem of Compensating Spectra and Closed-Loop Spectra for Decentralized Control Systems with Direct Control Feedthrough
带前通的分散系统补偿谱与闭环谱相交问题

In this paper, the intersection problem of compensating spectra and closed-loop spectra for decentralized systems with direct control feedthrough is studied by the properties of singular decentralized systems. With the concept of vanishing, necessary and sufficient condition is got for the problem. Moreover, the intersection of compensating spectra and its closed-loop spectra are also obtained when the conditions fail to hold.
