Abstract:
Uncertainty, limited state information, faults, and nonlinearities pose fundamental challenges
in the control and monitoring of complex dynamical systems. This talk presents selected con-
tributions to advanced control, estimation, and monitoring methods for uncertain nonlinear
systems, together with representative engineering applications. First, an observer-based adap-
tive fuzzy control framework is presented for nonlinear systems subject to multiple uncertain-
ties, including unknown nonlinear dynamics, actuator nonlinearities, external disturbances,
and unavailable states. The discussion then extends from state estimation to simultaneous
state and sensor-fault estimation, where adaptive fuzzy approximation and robust observer
design are combined to address unknown nonlinearities and disturbances. The third part fo-
cuses on prescribed-performance control, with particular emphasis on asymmetric perfor-
mance constraints and predefined-time achievement of the desired tracking performance,
allowing transient and steady-state tracking requirements to be specified explicitly. Finally,
optimization-based fuzzy and fractional-order control is illustrated through pitch control of a
large-scale wind turbine, with consideration of robustness, control performance, and mechan-
ical loads. The talk concludes with perspectives on integrating model-based control and esti-
mation with system identification and data-driven methods for process monitoring and fault
diagnosis, toward reliable control and monitoring of complex engineering systems under un-
certainty.
