中文说明：quadrotors，像几个不同的动态系统进行控制，具有未知的或缓慢变化的参数。要控制这个问题，可以使这样的系统不稳定，更难。自适应控制是一个令人钦佩的候选人与参数不确定性的存在跟踪期望的输出信号的能力。
English Description：
however. quadrotors, like several different dynamic systems to be controlled, have unknown or slowly varying parameters. this problem could make such system unstable and harder to be controlled. adaptive control is an admirable candidate for its capability of tracking a desired output signal with the presence of parametric uncertainties.
