Abstract: A kind of stepmo tor contro l system is designed based on PLC, which translates the angu lar
displacement of the stepmo tor to linear d isplacement bym in igearbox, and consequent ly drives the linear flex iblefram e
work. The system canmeet the requ irement ofm illimeter level and has the character istics o f simple configuration, steady
performance, good f inanc ial va lue and feasib ility.
