The invention discloses a forced diversion control method which includes first conducting diversion nominal track design according to a designated diversion period, conducting subsection planning on a motor-driven path based on error boundary and adopting a single pulse control method based on C-W guidance rate in each section to achieve track tracking of the subsection planning route to form a single side limit cycle. The method completely utilizes diversion largest error boundary, plans movement track in an error boundary and controlled diversion track moving tread, achieves quick diversion, saves fuel consumption and has strong engineering practicalness.
