We have previously shown that region 2 energy capture can be increased by using adaptive torque gain control on variable speed turbines. This adaptive torque control works by compensating for unknown and time-varying aerodynamic parameters such as the maximum power coefficient CPmax and its corresponding optimal tip speed ratio λ. This paper extends our earlier research in two ways in order to make the adaptive control technique more appealing to the commercial wind turbine industry. These two extensions are the use of the nacelle anemometer and the extension to a second-order discrete filter in the gain adaptation law. We believe that these two extensions will allow the adaptive controller to achieve its increased energy capture at lower cost and less sensitivity to noise than was possible with our original adaptive control strategy.
The problem of estimating a random signal vector x observed through a linear transformation H and corrupted by an additive noise is considered. A linear estimator that minimizes the mean squared error (MSE) with a cer...

The Smith predictor is applied to the boundary control of damped wave equations with large delays at the boundary measurement. The instability problem due to large delays is solved and the scheme is proved to be robust against a small difference between the assumed delay and the actual delay.
This paper presents a solution for the hardware implementation of EIA-709.1 Control Networking Protocol. It is the basic protocol of LonWorks systems that is widely used for the building system and the sensor system. ...
