Compared to other techniques, the proposed method has better performance in the tracking accuracy and speed, does not cause the overflow in the fixed-point arithmetic implementation, and is suitable for estimation of the time varying signal. 与以往的方法相比,该方法跟踪精度高且跟踪速度快,具有用定点实现其算法时不容易产生溢出和适合于时变信号的优点。
Applying wavelet denoise to improve the test signal, the dynamic characteristic parameters of a overflow valve were obtained by selecting characteristic point of the signal. 此系统应用小波降噪的方法提高测试信号的质量,然后提取信号特征点,得到溢流阀动态特性的各项参数。
