摘　　要：设计了一种新型大功率晶闸管整流装置智能数字触发控制器。该控制器硬件核心由基于16位微控制器MC9S12DP256B与TI DSP TMS320LF2407的双处理器系统构成。算法上采用模糊自适应比例积分(PI)进行稳流控制,整流变压器档位与控制角解耦控制优化功率因数。为满足该系统的实时性及高可靠性的要求,为主控制器移植了嵌入式操作系统μC/OS-Ⅱ。实验结果表明,采用该方案的智能数字触发器获得了令人满意的性能,主电路电流稳态精度高、抗干扰能力强、换档期间电流无冲击。An intelligent digital trigger is designed for large power SCR（Silicon Controlled Rectifier） unit. Its core is a dual-processor system based on 16- bit microcontroller MC 9 S 12 DP256 B and DSP（Digital Signal Processor） TMS 320 LF 2407. The software of fuzzy self-adaptive PI（Proportional Integral） is used to stabilize current and the decoupled control of rectifier transformer taps and control anger to optimize power factor. The operating system μC/OS-Ⅱ is embedded into microcontroller to meet the real time and reliability requirements. Experiment results show that the designed intelligent digital trigger has accurate steady current and strong anti-jamming capability,and there is no current imoulse during tap change.
