Abstract:
In this paper, we aim to modify the system which includes time-delay elements including closed loop system and uncertainty of the wind turbine system and time-delay elements. Time-delay will happen during the long distance communication. By observing and controlling the attitude of wind turbine system from distance, the transmitted control input and output signal will be delayed certainly. For this reason even thought wind turbine system is a stable system, but it will be an unstable system by time-delay elements. So, here we consider about the IMC method which is one of the robust controllers. IMC method is composed of optimum controller and uncertainty model of control object and time-delay elements. The optimum controller is designed by minimizing the coefficients of external disturbance of output signal by H2 norm in order to stabilize the closed loop system considering the uncertainty of control object and predicted time-delay element and at the same time minimize the effects of
time-delay element in sensitivity function. In this research controlling of the angular velocity and pitch angle of bale is considered. In order to have a stable angular velocity, we implied Internal Model Controller. As consequences, angular velocity converges to reference signal with good performance.
