In the first part. firstly we introduce a new class of semigroup s called r - unipotent e - inversive seniigroup. serondly we describe the strong congruences on s in terms of their kernels and traces. ve prove that a strong congruence on s can present a strong congruence pair : conversely. a strong congruence pair on s can determine a strong congruence
接著用「核-跡」方法研究s上的強同余,即證明s上的任一強同余,可以決定s的一個強同余對,反之s的任一強同余對,可以決定s上的一個強同余。 -
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 ) 。
