Abstract�� The approach of implementing the field-oriented vector control to AC linear motor was studied based on the analysis of the vector control principle. An experimental system of linear motor control system was built for testing by use of PC and special AD/DA board as the control system hardware. The control program was developed in C language, which includes initializing module for the initial parameter calculation, real-time interrupt service module for the feedback sampling and vector control calculation and handle of I/O, and other interface modules, etc. The experiment pictures of the positions of the motor in the initialization stage, the linear velocity and the positions of the motor in position closed-loop state, etc, were shown separately. The testing results demonstrate that the approach of the field-oriented vector control developed for an AC linear motor driving table is valid and realizable.
