摘　　要：以液压型风力发电机组调速系统为研究对象,针对变量马达的恒转速控制问题,结合动态矩阵控制(DMC)原理,提出一种基于DMC的液压型风力发电机组调速系统预测控制方法,并通过Simulink-AMESim联合仿真技术分析预测步长与控制步长对转速控制的影响规律。研究结果表明,与经典PID控制方法相比,基于DMC的预测控制方法提升了液压型风力发电机组调速系统的控制性能,可为后续工程实际应用提供理论指导。In view of the constant speed control problem of variable displacement motor,this paper proposes a hydraulic wind turbine speed control method based on the dynamic matrix control(DMC)prediction control,and analyzes influence of predicted horizon and control horizon on the speed control using the Simulink-AMESim. The simulation experimental results show that the DMC-based predictive control method improves the performance of the hydraulic turbine system speed control and provides theoretical guidance for subsequent engineering application.
