In order to luminosity increase in VEPP-4 collider at BINP, it was acceded to increase the current in four-bunch mode (2е-2е+) from 5мА up to 30мА in each bunch. One of the problems on the way to current increase is instability associated with longitudinal bunch oscillations. A feedback system is being developed for bunch oscillations control. The feedback system consists of two identical parts, each works with separate amplifier of 100 W and deals with only one type of particles. Each part contains two channels: one for damping of inphase oscillations, another for damping of antiphase oscillations. Decrement due to the feedback system is about 3000 1/s, that exceeds the decrement due to radiating losses approximately by 180 times.
