摘要
本文简要介绍了基于电压负反馈和电流正反馈的直流调速控制原理,分析了带电压负反馈和电流补偿控制调速系统的数学模型,着重分析和讨论了系统的稳定性,证明了全补偿的条件就是系统临界稳定的条件。并且就参数变化对控制系统的影响作了全面分析。
The paper introduces D.C.variable speed control principle based on electric current positive feedback with voltage negative feedback, analyses the mathematics model of variable speed control system with voltage negative feedback and current compensate, and emphasizes the importance of analysis and discussion of the system＇s stability, proves the conclusion that condition of complete compensate is the condition of the system critical stability, and analyses comprehensively the effect of what the control system accepted for parameter＇s change.
