Description: 具有较大代数免疫度的布尔函数在一定程度上可以抵御代数攻击，但是也许不能抵御快速代数攻击。为了研究布尔函数抵御快速代数攻击的一般性质，对 元布尔函数提出了 -快速代数免疫性的概念，其中e为正整数且1==n-e则称f具有e-快速代数免疫性。对于每一个正整数e=1,...,n/2p-1如果一个布尔函数都具有e-快速代数免疫性则该布尔函数是抵御快速代数攻击的最优布尔函数。讨论代数免疫度和e-快速代数免疫性之间的关系以及具有e-快速代数免疫性的充分必要条件。构造一类具有1-快速代数免疫性的 元布尔函数。提供一个判断e-快速代数免疫性的算法。当利用该算法来判断布尔函数抵御快速代数攻击的最优性时，该算法比Armknecht等给出的算法具有更好的计算复杂度。-With large algebraic immunity of Boolean functions to a certain extent, to resist algebraic attack, but may not withstand the fast algebraic attack. In order to study Boolean functions of algebraic attacks against the general nature of fast, on the proposed element Boolean functions- fast algebraic concept of immunity, in which e is a positive integer and 1 == ne f with e-called fast algebraic immunity. For each positive integer e = 1 ,..., n/2p-1 If a Boolean function has a quick e-algebra is the Boolean function immunity against fast algebraic attack is the best Boolean function. Discussion of e-algebraic immunity and the relationship between the algebraic immunity quickly and with e-fast algebraic necessary and sufficient conditions for immunity. Construct a Class 1- meta-fast algebraic immunity of Boolean functions. Provide a fast algebraic immunity to judge e-algorithm. When using this algorithm to determine the Boolean function fast algebraic attacks against the optimality, the a

Description: ：针对传统矩阵变换器存在电压传输比低和输出性能易
受非正常输入影响的两个固有缺陷，提出一种Z–源双级矩
阵变换器(Z-source two-stage matrix converter，ZSTSMC)及
其调制方法。利用Z–源网络的升压特性以提高电压传输比，
通过Z–源网络电容电压闭环对直通因子进行自适应地调
节，从而有效抑制非正常输入对输出性能的影响。闭环控制
中采用一种非线性PID 算法，削弱了Z–源网络表现出的非
最小相位特性带来的不良影响，提高了系统动态性能和抗扰
能力。仿真和实验验证了该拓扑的可行性和正确性。-A novel Z-source two-stage matrix converter
(ZSTSMC) and its modulation strategy were proposed to
overcome two main drawbacks of conventional matrix
converters, i.e., low voltage transfer ratio and low immunity to
abnormal input voltages. The Boost voltage characteristics of
Z-source network was introduced to improve the voltage
transfer ratio. The shoot-through index was adaptively
controlled by Z-source capacitor voltage closed-loop, so as to
be immune to the disturbance of abnormal input voltages. The
nonlinear PID controller was employed to eliminate effects
caused by non-minimum-phase characteristic presented in
Z-source network and to improve the dynamic performance
and robustness of the system. Finally, the validity and
feasibility of this topology were verified by simulation and
experiment results.
