A study on simulation using Matlab shows the dynamic condition of a beam on feed-back with encorder. A controller for rapid response interpreted the stability on simulation with pole-placement technique The effect of response was considered feed-back gain, The result of feed-back is described that various feed-back coefficient shows stable controll systems, It would be expected each result according to controllers,

I.G.G is abbreviation for inert gas generator high temperature in cargo tank it desulfurize, exhaust and froze the gas that combined brimstone element and soot, then supply inert gas by blower and mack tank inside incombustible range this is equipment that nip in the bud the explosion. The blower for suppling inactivated gas has big impeller with heavy weight to achieve the high pressure, it causes a delay for first operation time and too much load is delivered to motor, total destruction by fire of motor is happen frequently. On this research, we will reduce the size and weight of impeller and install it with several stage, it makes an effect for reducing the first operation time. We also intend to contribute to efficient I.G.G. blower design by research a flow rate and pressure specialty from the diameter of impeller number of blades and size of casing.
