A microprocessor-based adaptive pulse-pump controller (μP-APPC) for X-Y mode frequency-locked stepping position servo control system (XY-FLSPS) is proposed. A control strategy in μP-APPC for fasting the system locking process is developed. A discrete frequency set is built to represent the servo position so as to raise the accuracy of position lock and reduce the conversion error in the signal processing. The μP-APPC can respectively provide proper X's and Y's motion profiles for guiding their movements according to the detected position errors. An X-Y pulse rate identifier (XY-RI) is built to prescribe the instant X-axis and Y-axis motion speeds so that both X and Y motors can reach the target at approximately the same time. System modeling for analysis and computer simulation is constructed. A prototype of the XY-FLSPS with μP-APPC controller is developed for assessing system performance, and the X-Y position and speed responses are described by three-dimensional display.
