摘　　要：根据分数阶系统扩展频域分析法对分数阶相位超前校正器进行建模,这一结构能使该校正器与传统整数阶校正器一样为原系统提供一个零点和一个极点,具有任意阶次超前校正器的统一化形式.给出扩展频域超前校正器的解析法设计步骤,并和一般频率域下不同结构的分数阶超前校正器的适用性作了分析比较和性能仿真.The fractional-order lead compensator provided in this paper is modeled by extended frequency analysis for fractional systems. It has a new structure which gives the original system one zero and one pole definitely like the integer order, and can be regarded as a generalized form of conventional compensators with arbitrary orders. Its analytical design method is given. Also, comparison and simulation are made between two fractional-order lead compensators with different structures in common and extended frequency domain.
