To one of defining factors of work collider VEPP-4M is efficiency of injection of bunches from store-preaccelerator VEP-3. It depends on many parameteres, including stability of an orbit of particles in the injection region. The system of correction including the control not only a current, but also magnetic fields has been developed for orbit stabilisation at injection time in corrector magnets. A proportional-integral-derivative controller (PID controller) is applied to increase of accuracy and speed of installation of a orbit.
