摘要
针对带电流截止负反馈电压闭环直流调速系统的不足,在对原系统改进的基础上,提出了一种新的基于电压控制策略的直流调速系统:电压/电流双闭环直流调速系统。文中较详细地分析了改进后系统的工作原理,同时对改进前后的系统进行了对比仿真研究,仿真结果表明,改进后系统的动态性能,特别是起动性能得到了改善。
According to the deficiency of the voltage closed-loop speed regulation system with the end current, and on the basis of improving the primary system, this paper puts forward a new kind of direct current speed regulation system based on voltage control strategy: voltage/current double-closed-loop direct current speed regulation system. The principle of work about the system is analysed particularly in this paper, and at the same time, the simulation research is performed between the improved system and the primary system. The result of simulation indicates that the dynamic capability of the improved system, especially the jump-start capability has been improved.
