초록

본 논문에서는 다기능 레이다(multi-function radar, MFR) 방위각 구동 장치(azimuth driving equipment, ADE)의 정지 모드를 위한 제동저항 설계를 제안한다. ADE는 중거리의 지대공 유도미사일과 유인 전투기 감시정찰 임무를 수행하며, 360도 전방향을 회전하는 회전 모드와 정지된 상태에서 피사체를 추적하는 정지 모드가 있다. 또한, ADE는 정밀 추적을 위해 규격시간 내에 회전 모드에서 정지 모드로 전환해야 한다. 하지만, 감속 시 발전기로 동작하는 영구자석 동기전동기(permanent magnet synchronous motor, PMSM)에 의해 입력 전원이 소손될 우려가 있으며, 이를 보호하기 위해 PMSM의 역기전력을 소모하는 제동저항 설계가 필요하다. 본 논문에서는 방위각 구동 장치를 구성하는 PMSM의 감속에 의해 발생하는 역기전력을 소모하는 제동저항 설계 방안을 제안한다. 시뮬레이션 결과를 통해 제안하는 설계 방안 및 효과에 대한 타당성을 입증한다.

In this paper, a design of dynamic braking resistor for stationary mode of azimuth driving equipment (ADE) for multi-function radar (MFR) is presented. The ADE carries out missions which is the rotation mode for all directions and the stationary mode for tracing a subject with standstill. The ADE has to transfer the operation mode in demand time from rotation mode to stationary mode for precise target tracing. During the transition with deceleration, it may cause the fault of input power device due to back-electromotive force (back-EMF) of PMSM with generator mode. To protect the power device, a design of dynamic braking resistor is essential for consuming back-EMF. This paper presents the development of dynamic braking resistor for consuming back-EMF of ADE with deceleration mode. The validity and effect of the design is verified using simulation results.
