Design & realization of control system of rendezvous and docking simulator

The Integrated Design of Control System of the Rendezvous and Docking Simulator (RVDS) was discussed. According to the structure of servo control, the realization of the hardware and control method was introduced in detail. The schemes of control system bases on the mechanism of distribution control system, and that can achieve separated control and centralized management. A nonlinear controller is presented, which consists of a feedforward controller and a disturbance observer. Simulation results demonstrate the effectiveness of the proposed algorithm.
