摘要
针对红外热像仪对调焦机构高精度、高可靠性的要求,本文提出了一种基于模糊控制的步进电机开环调焦控制系统。该系统主要由TMS320F28069微控制器、TMC260步进电机驱动芯片及外围电路构成。为了实现调焦系统精确定位的需求,文中陈述了基于模糊控制的步进电机速度控制策略,给出了系统的硬件电路设计。经过实际测试,结果表明该系统可以满足实际使用要求。
To address the requirements of high precision and high reliability in focusing systems of infrared thermal imagers,this paper proposes an open-loop focusing system for stepper motors based on fuzzy control.The system is composed of a TMS320F28069 microcontroller unit,a TMC260 stepper motor driver,and a peripheral circuit.In order to fulfill the precise positioning requirements of the focusing system,a speed control strategy is proposed for the stepper motor based on fuzzy control,along with a description of the hardware circuit design.Our experimental results confirm the feasibility of the system for practical use.
