摘要
用小波多分辨分析方法对EAST快控电源控制信号进行分解,分层设定阈值滤除不符合要求的频率成分再进行信号重构,得到了满足要求的EAST快控电源控制信号,并经过了仿真和实验的验证。结果表明,使用小波变换比使用其他方法更为理想。
The control signal of fast control power supply (FCPS) in EAST tokamak is decomposed using wavelet multi-resolution. The control signal of FCPS satisfied the demand is obtained, and verified by the simulation and test. Results show that the effect using wavelet is better than other methods.
