The time-of-flight neutron scattering spectrometer in CSNS(China Spallation Neutron Source) will use a bandwidth-limiting(BWL) neutron chopper for choosing neutrons of certain band ranges.Its control system should synchronize the phase signal of BWL neutron chopper with the timing signal from accelerator
and monitor operation status of the neutron chopper.In this article
we describe the structure of control system
the control principle
and the software design.Test results of the controlling accuracy and operation stability of the control system are given
