研究了不确定奇异分数阶系统的鲁棒稳定和镇定问题.在该系统里,状态矩阵的不确定参数通常假定为时不变和范数有界的.首先设计一个可预测的控制器使得不确定奇异分数阶正则;然后设计一个输出反馈控制器使得正则后的系统稳定,这样可以得到当分数阶阶次在[1,2)时系统鲁棒渐近稳定的充分条件;最后通过一个数值仿真证明了该方法的有效性. In this system, the uncertain parameters of the state matrix are usually assumed to be time invariant and the norm bounded. First, a predictable controller is designed so that the non-singular fractional order system Then the singular fractional order regularity is determined. Then an output feedback controller is designed to make the system stable after the regularity, so that a sufficient and sufficient condition for the system to be robust and asymptotically stable is obtained when fractional orders are [1,2]. Finally, a numerical simulation The validity of this method is proved.
