针对3D65CNC强力旋压机同步驱动过程中的两直线电机位置不同步的问题,采用变论域模糊PID控制方法对两永磁同步直线电机的位置误差进行补偿,设计了变论域模糊PID同步控制器。但单轴具有良好的伺服系统是双轴保持同步状态的重要前提,针对直线电机具有明显的非线性、不易对其进行精确的建模,采用无模型自适应控制和伪微分反馈( PDF)控制的方法对单轴直线电机进行控制。最后通过Simulink仿真证明该方案提高了同步控制的精度。

For the position synchronized problem of two linear motors in the synchronous drive process of 3D65CNC powerful spin?ning machine, the method of variable universe fuzzy PID control was applied to compensate position error of two permanent magnet syn?chronous linear motors, variable universe fuzzy PID synchronous controller was designed. But the single axis should have good servo system, which was an important prerequisite for biaxial synchronized state. Based on obvious nonlinear and hard to carry on the accurate modeling for linear motor, methods of model?free adaptive control and pseudo?derivative feedback control were applied to control single?axis linear motor. At last, the feasibility of the scheme was verified through Simulink simulation. The simulation results show that the scheme has improved the synchronization control precision.
