| Abstract: | The hydraulic wind turbine is taken as the research object, and the maximum power point tracking method
is studied to make the power tracking process stable. The feedback linearization method is used to solve the nonlinear
problem in this paper. With the pressure of hydraulic transmission as output, the controller of maximum pressure point
tracking is designed, and the solution of feedback linearization, which is combined with the traditional PID control to
solve the problem of depending on the model parameters, is proposed for engineering application. The simulation and
experimental studies are carried out on the 30 kVA hydraulic semi-physical simulation platform, thus the feasibility of the
method is verified, and it lays a theoretical and experimental foundation for the further research on hydraulic wind turbine. |
