Adaptive disturbance rejection control for nonlinear stochastic systems: an application to bioreactor system
نویسندگان
چکیده
In this paper, an adaptive scheduling H∞ disturbance rejection controller is designed for a class of nonlinear Markov jump systems with nonhomogeneous Markov jump process, in which the transition probabilities are time-varying. To estimate and reject the disturbance, a disturbance observer is considered, such that a disturbance rejection state-feedback control law is designed. Under the designed controller, a sufficient condition is presented to ensure that the resulting closed-loop system is stochastically stable and a prescribed H∞ performance index is satisfied. Finally, a simulation example is given to illustrate the effectiveness of the developed techniques proposed.
