With the rapid development of industrial automation, the normal operation of large industrial systems under unattended condition has become the research target. Considering the time delays occurred in the long communication channels, a set-valued observer (SVO) is utilized for the simplified wind energy conversion system to track and estimate an interval of states, which covering all allowed operating conditions. For the commensuration of the communication time delays, a delay operator is introduced to transform the system into an unstable linear-like system. Based on the SVO, a state feedback control law is studied by using Sylvester pole placement. The simulation results demonstrate that the states estimation errors of SVO are generally bounded to the given C-set, and superior to the Kalman filter.
