With the development of the electric power system, static - state reactive power compensators ca n ' t have met the requirements of the actual production and operation, and the trend to the fast and dynamic compensation for reactive power become greater and greater. since ertan hydroplant and 500kv transmission systems in sichuan power system have been operated, many power plants of load center are forced to halt during the high - water period, because the great deal of power is transmitted to far - distance load center. thus the load center loses voltage sustentation and the level of the system stabilization is debased greatly
四川電網的二灘水電站和500kv輸變電系統投入運行后，由於二灘水電站的大量電力遠距離輸送至負荷中心，迫使負荷中心的火電機組在豐水期大量停機，使負荷中心失去電壓支撐，大大降低了電網的電壓穩定水平；同時，因為四川電網中的無功補償裝置全為靜態無功補償電容器（或電抗器） ，這些設備只能在系統正常運行狀態下起到無功補償和電壓支撐的作用，而在電網出現事故時，不但不能起到電壓支撐作用，反而會促使電網電壓崩潰事故的發生。 -
The controlled object hyvp ( hydraulic pressure vibration platform ) has the property of big loading pressure and rating power, so it need considerable transmitted and control power, it also has the property of high - level math model, and narrow frequency width in closed - loop, and bad stability. this thesis is based on the hpvs in the “ tiema project ”
被控對象（液壓振動臺）具有負載壓力和額定功率相當大的特點，因此要求傳輸和控制的功率要相當可觀;而且它還具有數學模型階數高、閉環頻帶寬度窄、穩定性差等特點。 -

Future mobile communications have to support the transmission of high rate data and multimedia applications in the radio spectrum, which is already extremely scarce. the basic idea of adaptive coded modulation is to maintain a constant throughput by varying the transmitted power level, symbol transmission rate, constellation size, coding rate or any combination of these parameters. thus, without sacrificing bit - error rate ( ber ), these schemes provide high average spectral efficiency by transmitting at high speeds under favorable channel conditions, and reducing throughput as the channel degrades
自適應編碼調制（ adaptivecodedmodulation ， acm ）的基本思想是在不犧牲系統傳輸性能（比如ber ）為代價的前提下，通過單獨改變發送功率、波特率、編碼方案、碼率、調制方式，或者是綜合改變前面所述的各種參數，在有利的通道條件下，獲得較大的吞吐量，當通道質量下將時，相應地降低傳輸速率，最終達到提高平均頻譜效率的目的。
