Case Study: Korea Aerospace Research Institute achieves halved development time and simplified DO‑178C compliance with MathWorks' Model‑Based Design (MATLAB & Simulink)

Korea Aerospace Industries Develops Helicopter Active Vibration Control System Software to DO-178C Standards

Korea Aerospace Research Institute (KARI), working with Korea Aerospace Industries on a helicopter active vibration control system (AVCS) for the LCH/LAH program, needed to develop and verify DO‑178C/DAL‑C–compliant control software under a tight schedule and with limited embedded‑software experience. To avoid costly hand‑coding errors and speed verification, they adopted MathWorks tools such as MATLAB, Simulink, Embedded Coder, and the Simulink toolchain for Model‑Based Design.

Using MathWorks’ Model‑Based Design workflow (Simulink, Stateflow, Simulink Check/Coverage/Requirements and Embedded Coder), the team modeled, simulated, and verified control and runtime identification algorithms, auto‑generated about 7,000 lines of C, and executed SIL and PIL tests. The MathWorks‑based solution halved development time, minimized design iterations, simplified DO‑178C compliance, and produced traceable, verifiable code ready for integration and certification.
