A Cyber-Physical System (CPS) is defined as integrations of computation and physical processes. In CPS, small embedded devices are used to monitor and manage the physical process. Because of these physical devices with limited resources, it is impossible to perform complex calculations and processing. In view of this situation, we apply Service-oriented Architecture (SOA) concepts to CPS, called a...
Pitch system is a complicated nonlinear system disturbed by many uncertainties and is a key part of wind turbine system. When wind speed exceeds rated cut-in speed, pitch angle is changed to control wind power conversion efficiency, thus capturing rated power from wind and protecting wind turbine from damage. In this paper, based on the analysis of wind turbine aerodynamic, an active disturbance rejection...
