“…Most frequently, one desires to place the sensors so as to be able to estimate the states or system parameters [2,16,18,19] or to detect the changes in the system behaviour [1]. The latter aspect is strongly connected to fault detection and isolation problems [3][4][5][6][7]. The problem considered in this paper falls into the last category.…”

The paper addresses the problem on sensor location regarding the solvability of the disturbance decoupling problem by the dynamic measurement feedback (DDDPM). Both, the discrete-and continuous-time nonlinear systems are considered. An exact formula is given to compute a controlled invariant vector function, necessary for the solvability of the DDDPM. Then, two methods are given to find a measured output, which guarantee the solution to the DDDPM. The results are illustrated by several examples.
