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.%以液压型风力发电机组为研究对象，为使功率追踪的过程平稳，研究机组的最佳功率追踪控制方法。本文利用反馈线性化方法解决系统非线性问题，以液压系统压力为控制输出，设计最佳功率追踪控制器，并提出一种反馈线性化方法的工程应用解决方案，即结合传统PID控制解决反馈线性化工程应用中依赖模型参数精度的问题。依托30 kVA液压型风力发电机组半物理仿真实验台进行仿真和实验研究，验证了该方法的可行性，为机组进一步研究奠定理论与实验基础。
