The Flight Control HIL Interactive Simulation Solution is an integrated verification platform composed of a flight control hardware-in-the-loop (HIL) simulation system, simulator cockpit, three-axis turntable, five-axis turntable, load simulators, total pressure simulator, and navigation simulator. It is designed to support flight control algorithm research, system performance assessment, and human-in-the-loop validation. The system enables comprehensive verification of flight control algorithms, software, computers, control mechanisms, surface load simulators, and atmospheric sensors, significantly improving integration efficiency while ensuring system reliability and safety.

The solution supports full digital real-time simulation and enables semi-physical simulation tests with actual devices such as flight control computers, servos, integrated navigation systems, atmospheric sensors, servo load simulators, turntables, navigation simulators, and total pressure simulators. It allows full-system closed-loop verification within the physical simulation range, ensuring high-level coordination between flight control software and hardware.

Technically, the system is based on the HRT HIL platform and employs a real-time fiber-optic reflective memory network to construct a distributed simulation system with 256MB onboard memory, supporting at least 12 simulation nodes and no fewer than 3 closed-loop simulation nodes to meet real-time data exchange requirements. The platform enables real-time loop simulation with the flight control computer with a minimum step size of 1ms for high-dynamic full-system simulation. It supports Matlab/Simulink graphical modeling and converts Simulink models into embedded real-time code running on a real-time operating system, covering the full process from mathematical modeling to code generation, automatic loading, run control, model variable monitoring, online parameter adjustment, and data storage.

The system provides batch simulation and automated testing capabilities, industrial-standard bus simulation interfaces, and a VxWorks real-time OS for autonomous interface expansion. Physical devices such as simulator cockpits, three-axis and five-axis turntables, and six-channel load simulators provide realistic pilot operation, servo action, and load simulation experiences. The total pressure simulator replicates aerodynamic effects, while the navigation simulator supports BDS/GPS signal emulation, and the visual display system offers flight scenario rendering and lab-wide data visualization.

The main control system can flexibly configure and manage all physical simulation devices, ensuring safety during operation. A real-time network middleware provides unified management of devices from different vendors, offering robust scalability. Deterministic real-time control and an intuitive human-machine interface enable unified management of lab equipment and experimental data, integrated with data management systems, and accommodate future simulation and interface expansion needs.

Functionally, the platform enables mathematical simulation verification of flight control software or control laws, integrating flight control computers, simulator cockpits, servos, and load simulators into closed-loop simulations. The system supports flight visualization, satellite navigation simulation, total pressure simulation, and atmospheric sensor inputs to ensure realistic and reliable closed-loop experiments.

This solution is ideal for large-scale laboratories in the aerospace and aviation sectors, providing a comprehensive, high-precision, and extensible platform for flight control algorithm development, system integration, performance evaluation, and human-in-the-loop testing.
