双变量交一交变频器调速量化控制算法研究
Quantization algorithm of double-variable control AC-AC converter
摘要
Abstract
The angle α and the pulse width β of SCR are accurate parameters used in Double-Variable Control Theory (TVCT) AC-AC VVVF system. This paper introduces the fundamental principle of TVCT and puts for- ward a quantization algorithm of the angle α and the pulse width β. Using the TVCT and the quantization algo- rithm, the converter does not need a device for zero-crossing detection. Due to the inherent complexity along with high accuracy and good real time requirements of AC-AC VVVF system, one kind of frequency variable speed regulating control system based on microprocessor and CPLD is designed. The system based on the quantization algorithm is implemented. Finally, the corresponding experiment results of the system are corried to out verify the validity of the presented scheme.关键词
