Examples
- An algorithm about calculating frequency of motor vehicle brake oil pressure
一种计算汽车制动油压波动频率的算法 - The circumference mfl of the wire rope has a broad space - frequency range along the axial of rope
钢丝绳周向漏磁信号沿绳长有丰富的空间波动频率成份。 - By applying dwt and mallat in wavelet analysis , the oscillation signal of active power on transmission line is decomposed and reconstructed ; the strategy of upfc ' s secondary control based on wavelet is proposed by using the reconstructed active power as input signal . simulation results verify the efficiency of damping subsequent swing quickly under serious power oscillation circumstance that is hard to damp by ordinary upfc controller . the system dynamic stability is apparently enhanced
针对系统功率波动频率较高情况下upfc对系统后续摆稳定的控制作用难以得到充分发挥的情况，采用小波分析的mallat塔式算法对系统功率波动信号进行分解，并基于mallat塔式重构算法的思想滤除了信号的冗余扰动成份，寻找到一个高压缩比、低相对误差的重构功率信号，从而使其能够符合upfc实际控制需要。
