摘要
介绍了卷取机的张力控制系统结构,研究了磁粉制动器原理并推导出其数学模型.提出了一种基于ATmega16单片机的PWM技术和ICL7107电流检测的混合式补偿的实用恒张力控制系统,同时还给出了系统原理框图和电路原理图及张力控制流程图.
The structure of winding tension control systems and the principle of magnetic power brakes are introduced. The mathematic expression of the current from the control system of the magnetic powder brake is given. Using the composite compensatory technology of PWM in the ATmega16 microchip and the current measuring of ICL7107 chip, a practical constant tension control system is put forward. Its systematic principle map, circuit system, and tension control processing chart are given.
