The three control systems respectively were as follows : ( 1 ) the measuring part of the first one was displacement piezoelectric sensor. a pair of piezoelectric sensor / actuator was collocated by each side of the first solar array plate. the compensator was h ( s ) = 2395 - s ; ( 2 ) the measuring part of the second one was also displacement piezoelectric sensor. a pair of piezoelectric sensor / actuator was collocated by each side of the whole solarfan. tthe compensator was h ( s ) = 244s ; ( 3 ) the measuring part of the third one was velocity piezoelectric sensor. a pair of piezoelectric sensor / actuator was collocated by each side of the three solars array plates near to the body of satellite
三種控制系統分別是： （ 1 ） 、採用壓電位移傳感器，壓電傳感器驅動器對同位布置於內板的邊緣，控制器補償函數為h （ s ） = 2395s ~ （ 1 2 ） ； （ 2 ）採用壓電位移傳感器，壓電傳感器驅動器對同位布置於整個太陽帆板的邊緣，這是一種理想的情況，控制器補償函數為h （ s ） = 244s ~ （ 1 2 ） ； （ 3 ）採用壓電速率傳感器，壓電傳感器驅動器對同位布置於靠近星體的三塊基板邊緣，控制器補償函數為h （ s ） = 2370s ~ （ 1 2 ） 。 -
The antenna pointing control is open loop control without feedback. the antenna pointing errors due to antenna tracking motion and satellite attitude adjusting ( trusting ) were analyzed, as well as the influence of damping, tacking velocity and trusting time
文章分析了天線作跟蹤運動和星體作姿態調整時，對星體姿態控制精度和天線的指向精度影響，同時分析了阻尼、跟蹤速度、噴氣脈沖寬度等因素變化對動力耦合程度的影響。 -
The acceleration may in turn be obtained from the velocity of the satellite and the radius of the orbit.
這個加速度又可根據衛星的速度和它的軌道半徑來求得。 -
Velocity measurement of satellite system
衛星測速系統 -
In an edt, the electrical power produced is the rate of work done by the magnetic drag ? that is, the magnitude of the drag force times the velocity of the satellite ( relative to the magnetized ionosphere ), which is about 7. 5 kilometers per second in leo
在edt中，生成的電功率等於磁拖曳力做功的速率，也就是拖曳力的大小乘上衛星相對于磁化電離層的速度，在leo上約為每秒7 . 5公里。 -
