PURPOSE:To provide a method for controlling a digital servo actuator which can accurately output a command signal corresponding to a real time to a driving locus function which is irregularly varied every moment. CONSTITUTION:A method for controlling a digital servo actuator which inputs a pulse as a command signal judges whether absolute values of a varied amount of next target value f (tp+n. t) from a target value fp at a latest time point tp of a pulse output at each infinitesimal time (tp+n. t) from the point tp of the pulse output is a resolution f(t) or more of the actuator or not. Thus, only if the absolute value of the varied amount is the resolution f(t) or more of the actuator, one pulse is output in an increasing or decreasing direction of a driving locus function in response to a code of the varied amount, and this time point is updated as a latest time point of new pulse output. |
