Abstract :
Extends the analysis results of linear periodically time varying controllers to general linear time varying (LTV) controllers. It is shown that linear time invariant (LTI) control provides strictly better control performance than linear strictly time varying control if l2 disturbance rejection of LTI plants is considered. The analysis is carried out in the frequency domain. This approach provides not only new results on disturbance rejection of LTV control but also some insight into the properties of general LTV systems
