Abstract :
In this paper, the loop transfer recovery (LTB) of P and PI observer-based controllers with two additional paths, direct output and output error feedback, are analyzed. We highlight the major differences and report new results which complement previous results in LTR theory. In particular, it is shown that proper modification of system structure leads to automatic generation of the aforementioned paths having static gains, and ELTR can be achieved by a modified full-order P observer even though a certain matrix is not full rank
