摘　　要：针对分布式系统中储能子模块平衡能量过程中的抖振问题,首先,引入新的组合函数代替幂次函数,并给出无抖振证明。然后,在传统的滑模面基础上设计了PID滑模面,减小系统的超调。同时,将组合函数运用于切换控制律中,设计新型的控制律。最后,在MATLAB/Simulink中搭建仿真模型,将传统控制与基于新型趋近律的滑模控制方式进行对比分析,验证了该方法在系统防抖振方面的优势。Aiming at the problem of the chattering of the storage energy battery in the distributed system,the exponential function was replaced by a new combined function.Afterwards,PID sliding mode surface was designed on the basis of traditional sliding mode surface to decrease the overshoot of the distributed system.In addition,a new reaching law was designed in the switching reaching law with the combined function instead of the exponential function.At last,the simulation model was built in MATLAB/Simulink.By comparing and analyzing the differences of the traditional control method with PID sliding control method,we can verify that the sliding control can decrease the chattering phenomenon.
