摘 要: 基于SVM-DTC算法的交流(AC)调速实验平台克服了传统控制算法的缺陷,具有较好的运行性能,但交流调速算法中存在一定的死区时间,并引起了相应的死区效应问题。针对以上问题,提出基于电流矢量的死区补偿原理,分析死区补偿策略,设计带有死区补偿的SVM-DTC交流调速实验平台。实验结果表明:该方法能够消除死区时间引起的死区效应问题,较好地改善系统的运行性能。
关 键 词: 电气工程;变频调速;SVM-DTC算法;零电流钳位;死区补偿

Abstract: The AC speed regulation experimental platform based on SVM-DTC control algorithm has overcome the shortcomings of traditional control algorithm, and the good operating performance has been verified in experiments. But the presence of dead-time in the AC speed control algorithm can cause the problem of dead-time effect. To solve the problems above, we proposed the dead-time compensation based on current vector, analyzed the dead-time compensation strategy, and designed AC variable frequency speed regulation experimental platform based on SVM-DTC algorithm with dead-time compensation. Experimental results show that the problem of dead-time effect caused by dead-time has been eliminated, and the operating performance of the system has been improved effectively.
Key words: electrical engineering; variable frequency speed regulation; SVM-DTC algorithm; zero current clamp; dead-time compensation
