摘　　要：恒流源在各种电子设备中的应用越来越多,其性能的好坏直接影响着整个设备的性能表现。为了充分利用智能控制方法提高使恒流源的性能,提出一种基于模糊控制的恒流源。本设计方案采用三星公司ARM9 S3C2410高速嵌入式微处理器作为恒流源的控制、显示和输出电流检测核心,运用模糊控制算法实时控制,实现20mA到2000mA高精度恒流源。In a variety of electronic devices, constant current source is more and more applied, and its performance directly affects the performance of the whole device. In order to improve the performance of constant current source using intelligent control method, a kind of constant current source is proposed based on fuzzy control. The design uses high speed embedded ARM9 S3C2410 from Samsung as the core of control, display and output current detection, and uses fuzzy control algorithm for real-time control, realizes a high precision constant current source from 20mA to 2000mA.
