本文提出当信道增益为时变函数时，利用自适应控制器来补偿信道增益的变化，以便在接收端能准确地恢复出信息信号。

In order to recover the message carrying signal at the receiving end, we use adaptive controller to compensate the variation of channel gain when the channel is time-varying.

本文考虑链路增益时变情况下的功率控制问题，给出了一个二进制反馈功率控制算法，并证明了算法的收敛性。

In this dissertation, a binary feedback power control is presented when link gains are assumed to be time varying and only one bit is sent back to each transmitter.

该控制律在簧载质量和非簧载质量的速度反馈上引入了时变的反馈增益，该反馈增益随路面激励主导频率的变化而实时调整。

The control gains which are tuned according to road frequency are used to the velocity feedback of the sprung mass and the unsprung mass.
