“…First, compared with the book of Boukas, observer is given in the form of conventional differential form instead of stochastic differential form, which is easier to implement in the practical process. Second, compared with the completely transition rates, the partly known transition rates are proposed to design the observer for Markovian jump systems, which cover completely known and completely unknown transition rates as two special cases. Third, compared with the literary works without stochastic disturbance, stochastic disturbance is considered for observer design of Markovian jump systems.…”
