Abstract	Rotary steerable systems (RSS) permit downhole directional control whilst continuously drilling in rotary mode. Rotary-steerable systems possess clear advantages both technologically and economically. The control principle of the servo platform in directional drilling system was studied. A control system composed of eccentric cam, dynamotors, platform control axis and electronic storehouse was designed. The inclination of wells was measured using acceleration sensors and a gyroscopes sensor. Experiments results show that the platform could keep itself stabilized and has good controllable and visible characteristics. Moreover, the system still has good tracing capacity when the drilling parameters change in a wide range.
