Abstract: This study proposes a torque pitch coordinated control method for permanent magnet wind turbines based on an improved artificial bee colony algorithm,which effectively improves the operational efficiency and stability of the units. A mathematical model for permanent magnet wind turbines is established, process it based on state feedback linearization theory,obtain a global linear model,and construct a pitch angle controller; reuse pole reassignment method to complete the construction of torque controller; reduce the dynamic torsional load of the wind turbine transmission system through torque pitch coordinated control; by using an improved artificial bee colony algorithm to optimize the controller parameters, the control effect is effectively improved. The experimental results show that this method can achieve torque pitch coordinated
control of permanent magnet wind turbines, with small fluctuations in pitch angle and low-speed shaft torque variations, stable output power with concentrated probability density function.
