To deal with filter value calculation instability, people put forward and carry out lots of methods in practice such as self-adaptive filter, fixed amplitude filter and square root filter, etc.
为了解决滤波器数值计算不稳定问题，实践中提出并应用了许多方法，如自适应滤波、固定增益滤波、平方根滤波等。
The paper introduces a self adaptive filter system which detects the current reference of active power filter quickly and accurately.
介绍了一种自适应滤波系统，用于快速准确地检测出有源滤波器的参考电流。
The self adaptive filter automatically adjusts the filter factors . When the adjustment achieves equilibrium , the output signals are almost equal to the raw ones.
金属补偿器实时对滤波系数自动进行调整，当补偿器调整达到平衡时，其输出信号大约等于失真前的原始发送信号。
The self adaptive filter can reshape downhole signals, and the distorted signals are compensated and rectified by software on surface.
其目的是对井下失真信号在地面进行软件补偿和校正 ，以克服电缆、温度等原因造成的信号失真。
