||Robustness is a very important topic in control-system design because real engineering systems are vulnerable to external disturbance and measurement noise and there are always difference between mathematical models and the actual system. In this thesis, we consider a robust stabilization problem over a new wind turbine generator system which was introduced in , the design process including modelling of uncertain system, robust stability and performance analysis, and robust controller design.|
The design objective for the system is to find an H∞ optimal controller, which ensures the maximum power and speed tracking erorr of the system to be small. In order to verify the controller, the MATLAB, Simulink, and DSP are used in this application. We realize the controller by the DSP, eZdSP F28335. The simulation results shows that the closed-loop system with H∞ optimal controller achieves a satisfactory level of robust stability and robust performance.
