The invention provides an automatic control system for a viscose impurity filter group, and the system can be used for solving the problem that various parameters need to be monitored to guarantee the operation of the filter group because control is complex in the prior art. An optimized control system is built to control pressure parameters, the technology of a plurality of filter groups and equipment operation states are monitored in real time, the control system is simplified, and the filter quality of the viscose is guaranteed.
