Title: method and apparatus for estimating inertia of servo-system
Inventor: SUK JUL GI
IPC: B25J15/02
Filed: 2000-02-11
Abstract: PURPOSE: An estimating method of inertia of a servo system is provided to estimate load inertia regularly with precision in a servo system having low strength or relatively large load inertia. CONSTITUTION: A servo controller sets the initial inertia value of a model plant(222) depending on characteristics of a plant(112). The plant is driven according to a predetermined torque command profile set by the characteristics of the plant. When a torque command is input to a torque control unit(100) from the servo controller, a subtracter(114) inputs torque deviation subtracting the feedback torque from the plant to a torque controller(111). Herein, the feedback torque is 0 in initial driving, and the torque command is adjusted to be the same as velocity output from the model plant by monitoring of output velocity from the plant. A model subtracter(224) subtracts the feedback velocity of the model plant from the velocity of the plant and outputs the velocity deviation. The feedback velocity is 0 in initial driving. A mode velocity controller receives the velocity deviation and outputs a torque command to the model plant. The model plant reduces the driving velocity according to the input torque command. If the output velocity of the model plant is not the same as the output velocity of the plant, the servo controller adjusts the torque command by monitoring the output velocity. Thereby, the output velocity of the plant is the same as the output torque of the model plant.

     여기서, 상기 간접냉각수단은 증발기(40)가 내장되는 축냉조(60)와, 상기 축냉조(60)에 저장되는 상변화물질(70)과, 상기 축냉조(60) 내부에 그 선단이 연결되며 타단이 냉동실(10a)과 냉장실(10b)로 연장됨으로써 상변화물질(70)의 축냉작용을 통해 냉동실(10a)과 냉장실(10b)의 열을 흡수하는 히트 파이프(62)(63)로 이루어지며, 냉동실(10a) 및 냉장실(10b)에는 히트 파이프(62)(63)에 의해 형성된 냉기를 순환시키는 송풍팬(64)이 각각 설치된다. 
     상술한 바와 같은 본 발명에 따른 냉장고에 의하면 기존과 동일한  냉동 사이클을 통해 증발기의 냉각작용이 이루어지고, 상변화물질(70)이 냉각됨으로써 축냉조(60)에 삽입된 각 히트 파이프(62)(63)의 일단 또한 냉각되며, 이러한 냉각효과가 타단으로 전달되어 냉동 냉장실(10a)(10b)을 냉각시키게 된다. 
     축냉조(60)에 저장된 상변화물질(70)은 그 특성상 압축기(20)의 작동으로 냉각된 다음에는 냉각상태가 어느 정도 지속되기 때문에 압축기(20)의 작동이 멈추더라도 히트 파이프(62)(63)를 통해 냉동 냉장실(10a)(10b)의 열을 계속해서 흡수함으로써 냉각작용을 수행하게 된다. 
     따라서, 상술한 바와 같은 본 발명에 따른 냉장고에 의하면 첫째, 상변화물질 및 히트 파이프를 이용한 축냉작용 및 열전달 작용에 의해 압축기의 잦은 단속 조작없이 효과적인 온도 제어가 가능하기 때문에 작동효율이 높고, 둘째, 냉동실과 냉장실이 차단된 구조로 이루어지기 때문에 공기가 순환하지 않아 음식냄새가 섞이지 않고, 셋째, 착상현상이 심하지 않아 냉동 냉장실 내부가 고습도 상태로 유지되어 음식물의 보조기간이 연장된다는 이점이 있다.
