Application Study of Information Integration in Aerospace Transportation Control System

Four integrated design methods are proposed from the point of information integration. For the integration of guidance and ballistic trajectory design, a simultaneous approach-based unified framework is developed for autonomous dynamic trajectory planning under complex constraints, the results showed that various constraint conditions can be handled in the framework to get high accuracy solution, and the key point can be the computational efficiency improvement. For the integration of built-in-test (BIT) and ground test system, some new techniques, i.e. bus interception, model and data-driven based automatic analysis, and system-in-the-loop integrated test based on high speed measurement bus have applied for responsive launch and reduction in engineers involved in technical support. For the integration of control and telemetry system, the function modules can be integrated, reused and reconstructed through a design platform, so as to lower the system cost and avoid overlapping investment. For the model-driven integration of software and hardware design, the algorithm, software and hardware can be designed in parallel and simulated in one environment, which allowed to do quantitative analysis for various schemes. The information integration technique will provide a new idea for the development of the basic theory research, system implementation and design methodology, and will enhance the autonomy and adaptability of the control system, expand the role of it, improve response and effectively reduce the system cost.
