The mathematical model of hydraulic variable pitch control system of wind turbine was built, the simulation analysis of system was conducted by using MATLAB/Simulink and its stability was verified. Its conclusion illustrate this hydraulic variable pitch control system model is feasible and its parameters are right. After adding PID correction link, the coefficients of PID controller was tuned based on ZieglerNichols method,which improves the dynamic property of the control system.
