The variable speed wind turbine generator exhibits serious nonlinearity, uncertainty and difficulty accurate modeling, conventional PID controller can't achieve ideal control effect. In this paper, an adaptive inverse control scheme based on neural network identification technology is proposed to solve the above problem. The scheme firstly uses online identification of one DRNN to obtain the Jacobian information of plant. On this basis, another DRNN identifies the inverse plant model which constitutes adaptive inverse control system as controller. The simulation results verify that the adaptive inverse control scheme has excellent adaptability and robustness, which can make the actual rotational speed of wind turbine rapidly track the set point to maintain the best tip-speed ratio in order to get maximum wind energy capture in the random wind conditions.

A Numerical Simulation has been conducted to investigate the mixing of coaxial jets with zero-mass-flux synthetic jet actuators, two arrays of which are placed side by side around coaxial jets and in the exit plane of the outer primary jet. Both the temperature field of the primary jet and mixing processes are studied at given temperature ratio. High-frequency forcing leads to increases in the radial extent of the jet and turbulent intensity in the near-field and increased turbulent dissipation. During the analysis, the influence of adjacent synthetic jets is also considered. The comparison is made between the control effectiveness of two arrays of actuators and that of an array of actuators. The results show both of the actuator’s configurations can result in the significant mixing enhancement, but the former exhibits more desirable.
