碩士 === 國立中山大學 === 電機工程學系研究所 === 106 === In practical applications, the wind power generation system may be affected by various factors.Such as model error, external interference, mechanical aging, resulting in the output of the system as expected, and even cause system instability.For this reason, I use the robust control theory to analyze the [1] proposed in the new wind power generation system.And the establishment of system mathematical model, uncertainty considerations, toughness stability and performance discussion and H infity optimization controller design, put forward a complete design process. The control objective set in this thesis is to make the generator effective connected to the grid.The use of servo motor control system speed control and power compensation, the generator output voltage phase, frequency, amplitude synchronized with the grid, in parallel with the grid.And the numerical simulation software MATLAB to establish a controlled system, digital signal processor DSP implement the controller. Through the data transfer between the two, complete the closed loop system architecture.The experimental results show that the control scheme proposed in this thesis can be effectively connected to the grid and has robustness.
