摘　　要：由于二次动态矩阵控制(quadratic dynamic matrix control,QDMC)算法中二次规划求解计算量大、实时性差等问题,难以满足液压型风力发电机组变量马达转速的高精度快速控制需求。该文提出一种双重速率二次动态矩阵控制算法(dual rate QDMC,DR-QDMC),将控制增量的求解分解为快速层和慢速层2个时间尺度进行,利用AMESim-Simulink/Matlab联合仿真平台构建液压型风力发电机组的AMESim仿真模型并研究分析DR-QDMC算法性能。仿真实验结果表明,DR-QDMC算法不仅可增强系统控制实时性,而且还能提升变量马达转速控制的快速性和抗扰性。Due to large calculation and poor real-time property in the Quadratic Dynamic Matrix Control(QDMC)algorithm,it is difficult to achieve high precision and fast control requirements of variable motor speed of hydraulic wind turbines. In this paper,a Dual Rate QDMC(DR-QDMC)algorithm is proposed to decompose the control increment calculation into two time scales:the fast layer and the slow layer. With the AMESim-Simulink/Matlab joint simulation platform,the simulation model of hydraulic wind turbine is constructed to validate performance of the DR-QDMC algorithm. The simulation experiments indicate that the DR-QDMC algorithm can enhance real-time capability,and improve rapidity and immunity of variable motor speed control.
