Abstract

The rapid prototyping process and development tool which enable the control law evaluation efficiently are needed to minimize the development cycle, cost and risk of aircraft flight control system. This paper describes a development process that integrates the designed control law into HETLAS to evaluate simulation effectively using nonlinear mathematical models. The desktop engineering simulator was developed using HETLAS for the piloted simulation evaluation of a various control modes and the procedure was developed, which quickly integrates the HETLAS into HQS(Handling Quality Simulator) and HILS(Hardware In the Loop Simulation) environments. This paper presents a rapid prototyping process using HETLAS that significantly shortens the integration process of the control law into the nonlinear math model, HETLAS, and allows the control law designs to be quickly tested in the piloted simulation and HILS environments.

항공기 비행제어시스템의 개발기간, 비용 및 위험도를 최소화시키기 위해서는 비행제어 법칙의 적용 및 시험을 효율적으로 수행할 수 있는 통합개발 도구와 Rapid Prototyping 프로세스가 요구된다. 본 논문에서는 Matlab/Simulink 환경을 통해 생성한 제어법칙 자동코드와 비행동역학 해석프로그램(HETLAS: HElicopter Trim, Linearization and Simulation)과의 연동 절차를 개발하여 시뮬레이션 평가를 효율적으로 수행할 수 있는 환경의 구축에 대해 기술하였다. 또한, 본 연구를 통해 제어법칙의 다양한 모드의 조종사 시뮬레이션 평가를 위해 HETLAS를 이용한 데스크탑 시뮬레이션 환경을 개발하고 조종성 시뮬레이터 및 HILS(Hardware In the Loop Simulation) 시험 환경과 효율적으로 연동하여 시험할 수 있는 절차를 개발하였다. 비행제어법칙 개발과정에서 HETLAS를 중심으로 한 해석/시험 환경을 개발함으로써 반복적인 제어법칙의 설계/해석 및 시험 절차를 효율적으로 수행할 수 있도록 하였다.
