摘要

研究了直流电机换向电枢电源的设计。设计了一种与高速数字信号处理器(DSP)相结合的大规模集成电路(LSI)点火电路，用于在与直流电机相连的双反并联三相变换器中，在0°到180°之间调节点火角，以实现正、负电流控制。采用前馈技术和变结构比例积分补偿器，得到了快速响应的电流控制器，在连续和断续电流传导下都能产生最优的电流响应。

A fast-response current controller for microprocessor-based SCR-DC motor drives

The design of reversing armature power supplies for DC motors is considered. An LSI firing circuit, in conjunction with a high-speed digital signal processor (DSP), has been developed to adjust the firing angle between 0 degrees and 180 degrees for both positive and negative current control in a dual antiparallel-connected three-phase converter connected to a DC motor. A fast-response current controller is obtained by using feedforward techniques and a variable-structure proportional-integral compensator to produce an optimal current response under both continuous and discontinuous current conduction.<>
