摘要
Abstract
Servo mechanism is the executing agency of control system,and frequency test is an important test content.In view of low speed and discrete frequency points of traditional sine point-by-point scanning signal frequency test,chirp signal is put forward to replace traditional test signal.Low-pass filter and wavelet packet transform method are used to filter out interference in the process of test with the anti-interference ability of the system improved,and the effectiveness of the testing method is verified by simulation.关键词
