The study of doubly-fed generator grid side PWM high-order sliding mode control
Aiming at the problem of doubly-fed generator parameters changing and the external disturbance’s influence on the grid side PWM, the traditional PI control in response speed and control precision on performance was not satisfactory. Due to the sliding mode variable structure control to external interference and internal parameters change were robust,this paper proposed the high-order sliding mode control grid side PWM to improve the PI controller’s deficiency.First of all, this paper introduced the mathematical model of doubly-fed generator grid side PWM, proposed the higher order sliding mode variable structure strategy to control it.From the simulation we can summarize that compared with PI controller,under the condition of internal parameters changing and the external disturbing, high-order sliding mode control can adjust the DC bus voltage rapidly and show the excellent dynamic characteristics.
