%X 为实现伺服压力机的柔性加工控制，在分析曲柄肘杆伺服压力机驱动系统的基础上，提出采用Bezier曲线数学模型的伺服压力机系统控制策略，并给出具体控制方案。给出了应用电枢电流有效值和初相进行控制的横向磁场驱动电机控制策略，建立了电机的伺服控制系统，对曲柄的运转进行精确的控制，最终将Bezier曲线数学模型计算得到的柔性加工给定曲线在滑块上实现。冲裁工艺柔性加工的模拟运行控制结果表明：控制系统能够获得满足加工工艺要求的精确滑块运行曲线。<br>In order to realize the flexible processing control of a servo press, the paper analyzes the drive system of a crank toggle servo press, proposes the servo press control strategy with the Bezier mathematical model, and gives the specific control scheme. Then it further proposes the transverse flux machine control strategy with the armature current RMS control and phase control and establishes the servo motor control system to precisely control the crank operation. Eventually the slider can be controlled with the flexible processing curves calculated by the Bezier mathematical model. The results on the simulation of punching process control show that the control system can achieve the precision slide operation curve, which is in agreement with processing requirements
