A kind derivative algorithm is discussed and the difference of numerical derivative and physical derivative is analyzed. What is more important is that the first step error problem is proposed and its bad affection to the system stability is shown by using a first order system as an example. Also the reason for unstable phenomenon is analyzed by using differential method. At last, detailed numerical simulation is given to shown the rightness of the proposed main conclusion.
