摘要
提出一种变论域模糊PID恒照度调光控制器,能自适应调变论域范围来消除模糊控制死区,其主控芯片为STM32F103C8T6。系统LED驱动器由AC/DC变换单元与KNX通信单元组成,适应宽电压输入范围交流电压90～265V,输出功率300W。测试结果表明,系统能效大于90%,稳定性好,恒照度控制精度比论域固定的模糊PID调光系统更高。
A type of variable^universe fuzzy PID constant illumination dimming controller, which can adjust the range of universe adaptively to eliminate the dead zone of fuzzy control, is put forward by using STM32F103C8T6 as the main control chip. The system＇s LED drive, composed of the AC/DC conversion unit and the KNX communication unit, adapts to a wide range of voltage input 90 265 V AC, with the output power being 300 W. The test results show that the system boasts high energy efficiency more than 90%, sound stability, and its constant illumination control accuracy is much higher than that of the fixed universe fuzzy PID dimming system.
