Abstract
This paper studies the fault detection problem of linear periodic systems. The aim is to design residual generators, which deliver a residual signal fully decoupled from unknown disturbances. First, a periodic parity relation based full decoupling residual generator with a periodic varying parity vector is designed. Then, a periodic observer based full decoupling residual generator is obtained. Examples are given to illustrate the achieved results.
