Abstract
The present disclosure discloses a two-point sampling optimized method and system for sinusoidal excitation-based frequency response measurement. A plurality of points are sampled at equal intervals within the starting frequency and ending frequency range as initial information, the interpolation error of each sub-frequency band is estimated according to existing sampling information, the sub-frequency band with the largest interpolation error is selected, two new sampling points are added within the sub-frequency band, and the above steps are repeated until the quantity of sampling points reaches the total quantity set by a user; and the user is asked whether new sampling points need to be added, if so, after the user specifies a new quantity of sampling points, the interpolation error of each sub-frequency band is estimated again and sampling continues, otherwise, the sampling ends. The present improves the practicality of a sinusoidal excitation-based frequency response measurement method.
