摘要
机场助航灯调光器的全数字控制采用DSP实现。该系统恒流调光器以TMS320LF2406 DSP为核心控制模块,片上自带的事件管理器EVA用于产生SPWM波形,10位A/D转换器作为光级给定和电压/电流输入接口,并通过PI数字电流控制器构成电流闭环系统。实验结果表明系统设计合理、运行可靠、具有优良的动静态性能。
The total digital control of the light dimmer in the airfield is based on DSP. The TMS320LF2406 DSP is taken as the core control module of the system constant-current dimmer. EVA is used to generate SPWM. The A/D converter （10 bit） is adopted as the input interface of light grade and voltage/current. The current close loop system is created through the PI digital current controller. The experimental results show that the system is designed reasonably, which can operate reliably and has good dynamic and static performances.
