【摘要】 瓦楞纸板横切机,用于对生产线上连续产出的瓦楞纸板进行动态定长剪切,俗称“飞剪”。要求剪切时切刀速度跟随纸板速度变化,即速度跟随;同时,在跟随过程中实现定长控制,即位置控制。因此,其“飞剪”控制是一个复杂的运动控制问题。为实现快速跟随,则要求驱动装置具有响应快,无超调,能快速停车定位。目前国内外还未见有专门的横切机驱动装置。直流驱动方式由于其换向器问题应用较少;普通变频器驱动方式难以满足快速性要求。本文主要针对横切机驱动系统开展设计与研究工作。论文以交流伺服驱动技术为基础,提出了一种智能型横切机伺服驱动器设计方案。主电路由三相整流模块和智能功率模块构成,控制电路采用DSP芯片TMS320F2812实现全数字化设计,利用DSP芯片PWM输出功能实现PWM控制。以交流永磁同步伺服电机数学模型为理论基础,提出采用电压空间矢量脉宽调制SVPWM与基于id = 0的转子磁场定向矢量控制相结合的方案,实现对横切机的驱动控制。软件设计利用模块化编程思想,针对横切机驱动系统特点,电流调节器采用常规PI控制算法,速度调节器采用模糊PID控制算法。仿真及试验结果表明该设计是有效,可行的,该驱动器有较好的速度跟随特性,满足系统要求,为高性能横切机整套设备的研制积累了经验。
【Abstract】 Crosscut machine of corrugated, used for the production line output corrugated cardboard dynamic fixed-length shear, commonly known as“flying shear”. When the shear, cutter speed must follow the change of the cardboard speed. In the meantime, it puts into effect fixed-length control. So flying shear is a complex motion control problem. To achieve follow quickly, drive unit is required to respond fast, no overshoot, parking position fast. At present, it also has no specific cross-cutting drive device at home and abroad. Because of its reverser problem DC-drive approach uses less. General inverter-drive approach can not meet the rapidity requirements. This paper mainly designs and researchs the drive system of crosscut machine. Based on AC servo drive technology, a smart cross-machine servo driver is designed in the paper. Main circuit is consisted of the three-phase rectifier modules and intelligent power module. TMS320F2812 DSP chip is used to control circuit to achieve digital design, completing PWM control. Modular programming ideas is used to complete the software design. Using voltage SVPWM based on the rotor magnetic field oriented id = 0vector control of a combination of programs finishes drive control. For features of the driver system, current regulator adopts PI control algorithm and speed regulator adopts PID fuzzy control algorithm. At last, the results of experiments and simulation show that the design of crosscut machine control driver is reasonable. The driver has good speed following characteristics to meet the system requirements. It accumulats experience for high-performance crosscut machine entire equipment design.
