| 为了解决锂电池组在长期使用过程中串联单体电池之间电压存在不一致的问题，提出了一种基于变论域模糊PID控制的级联式双向Cuk均衡电路系统。该系统采用级联式双向Cuk均衡电路实现了不相邻电池之间的均衡，采用变论域模糊PID算法提高了电池电压的均衡速度。为了验证该系统的可行性与优越性，在MATLAB/Simulink中设计了传统双向Cuk均衡电路和级联式双向Cuk均衡电路仿真模型，模糊PID算法和变论域模糊PID算法控制下的仿真实验结果对比表明，基于变论域模糊PID算法的级联式双向Cuk均衡拓扑的均衡时间比未加控制算法的传统双向Cuk均衡拓扑的均衡时间减少了64.29%；比未加控制算法的级联式双向Cuk均衡拓扑的均衡时间减少了50.82%；比基于模糊PID算法的级联式双向Cuk均衡拓扑的均衡时间减少了14.29%。系列仿真实验结果对比分析验证了基于变论域模糊PID控制的级联式双向Cuk均衡电路系统可以提高电池的电压均衡速率。 |

| During the long-term use of lithium battery packs, there is a problem of inconsistent voltages among the series-connected individual batteries. To solve this problem, a cascade bidirectional Cuk equalization circuit system based on variable domain fuzzy PID control is proposed in this paper. In this system, a cascade bidirectional Cuk equalization circuit is employed to achieve equalization between non-adjacent cells, and the variable domain fuzzy PID algorithm is exploited to enhance the voltage equalization speed. To verify the feasibility and superiority of the system, simulation models of the traditional bidirectional Cuk equalization circuit and the cascaded bidirectional Cuk equalization circuit were designed in MATLAB/Simulink. The comparison of simulation results under the control of the fuzzy PID algorithm and the variable domain fuzzy PID algorithm reveals that the balancing time of the cascade bidirectional Cuk balancing topology based on the variable domain fuzzy PID algorithm is decreased by 64.29% compared with the traditional bidirectional Cuk balancing topology without a control algorithm. The equalization time of the cascade bidirectional Cuk equalization topology without a control algorithm is reduced by 50.82%. The balancing time of the cascade bidirectional Cuk balancing topology based on the fuzzy PID algorithm is reduced by 14.29%. According to the analysis of the simulation results, it is demonstrated that the cascade bidirectional Cuk equalization circuit system based on fuzzy PID control in the variable theory domain can augment the voltage equalization rate of the battery. |
