摘要
张力控制是冶金、造纸、纺织等行业应用最为广泛的一项技术,它实现的好坏直接关系到产品生产效率的高低和质量的优劣。介绍了张力控制技术的基本原理,设计了一种以磁粉制动器为执行元件,基于AVR单片机的张力控制系统。采用类似PWM脉宽调制控制的方式,保证了系统的良好性能。实践证明,该系统具有良好的抗干扰性能,能够较好地完成控制效果,运行稳定可靠。
Tension control is a widely used technology in the areas of paper making, spinning and metallurgy. It is closely related with the products＇ production efficiency and quality. The basic principle of the tension control technology is introduced. A tension control system with a magnetic powder brake as the tension actuator is designed based on 8051 microcontroller. The mode similar to PWM pulse width modulation control is employed to guarantee the high performance of the control system. It has been found that this system has perfect performance of anti-jamming and can accomplish a rather better control.
