The observability gramian

SpletIn this paper, we first showed that the symmetric property of the Gramian matrix determines totally the observability property of any linear control system on a Euclidean space. Second, the natural extension of a linear control system from to … For finite-dimensional real vectors in with the usual Euclidean dot product, the Gram matrix is , where is a matrix whose columns are the vectors and is its transpose whose rows are the vectors . For complex vectors in , , where is the conjugate transpose of . Given square-integrable functions on the interval , the Gram matrix is: where is the complex conjugate of .

Empirical Observability Gramian for Stochastic Observability of

SpletThe reachability gramian is computed from the state impulse response and the observability gramian is obtained from the output response. The relation with the linear time invariant case is discussed and three di erent approaches for gramian computation are presented: the dual system approach, the empirical gramian approach http://control.asu.edu/Classes/MMAE543/543Lecture20.pdf
