A disturbance regulation feedback loop is added to state space controller in order to adapt the wind disturbances for wind turbine control systems, and a robust wind turbine speed controller is designed. The dynamic performance of wind turbine speed regulation is improved and mechanical loads are alleviated by proper design of the state-space feedback and DAC feedback parameters. The simulation results...
This paper presents an algorithm of Artificial Neural Network (ANN) pattern recognition method which is applied to the operations of wind turbine control system (WTCS). This paper presents two kinds of improved algorithms of Neural Network (NN) based on the basic principles to improve the convergence speed of the network. To avoid the network falling into the local minimum the genetic algorithm for...
A method of fault diagnosis and adaptive reconfiguration control based on dynamical recurrent neural network was presented for actuator loop in aeronautic propulsion system. Network weighted values were modified on-line to compensate for zero-deflection and uncertainty of actuator loop. The threshold-value differentiate method was applied for real-timely watching and diagnosing the actuator loop fault...
