摘　　要：为解决双轴进给驱动系统预测轮廓控制中,权重系数整定依赖人工经验和耗时较长的问题,本文提出一种双轴进给驱动系统有限控制集模型预测控制策略。首先将驱动电机的运动方程、电气方程和逆变器的数学模型相结合,建立统一模型;然后预测带有电流和转速信息的参考电压矢量;之后根据轮廓误差与跟踪误差之比,分情况来确定改进的价值函数;并进行备选电压矢量的选择和价值函数的寻优。最后,通过仿真研究证明所提出的控制策略能够满足所需的动态响应速度和轮廓跟踪精度,且无需权重系数整定。In order to solve the problem of reliance on manual experience and long time consuming for the weight coefficient setting in the predictive contour control of biaxial feed drive system,this paper proposed a control strategy for biaxial feed drive system based on finite control set.Firstly,the motion equations and electrical equations of the driving motor,the mathematical model of the inverter were combined to establish a unified model.Then,the reference voltage vectors with current and speed information were predicted.After that,the improved cost function was determined according to the ratio of contour error and tracking error,then the candidate voltage vectors were selected and the cost function was optimized.Finally,the simulation research prove that the proposed control strategy can meet the required dynamic response speed and contour tracking accuracy without the need for weight coefficient tuning.
