In this paper, by means of Lyapunov second method, we analyze the stability of IP control servo systems in the time domain for the first time. Based on the results of the stability analysis, the design rule to select the gain of IP control is suggested such that the maximum error of the output to the nominal system is guaranteed for all uncertainty and load variations. An example of a speed control of brushless dc motor is given to prove the unusefulness of the suggested gain design rule.
