Real-Time Simulation Platform Verification for RLV Attitude Control

The real-time simulation platform for reusable launch vehicle (RLV) to verify the finite-time attitude control is investigated. In this paper, a finite-time disturbance compensation attitude controller and a distributed virtual real-time simulation platform are proposed for RLV system with model uncertainty and external disturbances. Firstly, the multivariable disturbance compensation scheme is adopted to design a second-order sliding mode controller for the RLV, which can achieve the finite-time attitude tracking control. Furthermore, considering that the traditional simulation method cannot reflect the real-time attitude of RLV. The distributed real-time simulation platform (DRTSP) based on xPC system is proposed to verify the real-time performance of the designed controller. Moreover, based on the real time data obtained by DRTSP, a virtual space scene is established by Unity3D software which can show the real-time trajectory of RLV more intuitively. Finally, the simulation results from DRTSP and virtual space scene can demonstrate the effectiveness of the proposed control scheme.
