Abstract: A novel drive train for wind turbines with stepless speed regulation is studied in this paper. The noveldrive train consists of a planetary gear train and a hydrodynamic torque converter with adjustable guide blades. Thenonlinear dynamic mathematical model of the novel drive train with wind turbine is established on the basis ofhydrodynamics energy head theory. A fuzzy PID controller applied to the system is designed based on fuzzy theoryand PID control theory. Numerical simulation of the fuzzy PID controller is carried out by using MATLAB/SIMULINK softwre. Compared with the effect of the traditional PID controller, the fuzzy PID controller hasadvantages with higher precision and smaller overshoot. The results also indicate that the novel drive train based onfuzzy PID control can successfully realize stepless speed regulation with good stability and reliability. The hightransmission efficiency of the system is also proved.
