Abstract:

Trajectory sensitivity with respect to small random perturbations in initial state and plant parameters is investigated. An upper bound on the maximal spread around the nominal trajectory at time t for a probability level p is established in the paper. If a sufficiently high degree of exponential stability is attained by additional feedback, the modified system has a lower upper bound compared to that for the system without additional feedback. Moreover, when a deterministic observer is employed, the upper bound is increased but it is still lower than that corresponding to the system without additional feedback and without an observer.
