摘　　要：针对储能建筑系统在内部耦合现象以及外部复杂扰动的影响下出现的储能建筑系统输出电压不稳定等问题,提出了一种基于滑模控制和模糊聚类分析相结合的参数自适应滑模控制策略。根据储能系统双向传输变换器的拓扑结构,分析输出电压不稳定的原因,在储能变换器的控制环路中引入滑模控制,降低电压的期望值与实际值之间的误差,从而提升储能变换器的电压稳定性,并根据幅频特性分析法,对滑模参数变动对系统性能的影响进行分析,得到滑模参数的优化范围,为智能算法的整定奠定基础。为进一步提升系统的鲁棒性,引入模糊聚类分析技术,利用滑模规则和推导原理,对控制环路参数进行特征分析与特征提取,保证参数在多变环境中的优异性。为验证所设计的控制策略的正确性,建立储能建筑系统的数字实验模型,并设计基于自适应滑模的控制环路对其进行控制,与其他控制方法进行比较,自适应滑模控制下的输出电压具有较高的电压稳定性,为储能建筑系统的安全稳定运行提供了重要保障。A parameter adaptive sliding mode control strategy based on a combination of sliding mode control and fuzzy clustering analysis is proposed to address the unstable output voltage of energy storage building systems under the influence of internal coupling phenomena and external complex disturbances.Based on the topology structure of the bidirectional transmission converter in the energy storage system,the reasons for unstable output voltage are analyzed.Sliding mode control is introduced into the control loop of the energy storage converter to reduce the error between the expected and actual voltage values,thereby improving the voltage stability of the energy storage converter.According to the amplitude frequency characteristic analysis method,the impact of sliding mode parameter changes on system performance is analyzed,and the optimization range of sliding mode parameters is obtained,laying the foundation for the tuning of intelligent algorithms.To further enhance the robustness of the system,fuzzy clustering analysis technology is introduced,and sliding mode rules and derivation principles are used to perform feature analysis and feature extraction on the control loop parameters,ensuring their excellent performance in variable environments.To verify the correctness of the designed control strategy,a digital experimental model of the energy storage building system was established,and a control loop based on adaptive sliding mode was designed to control it.Compared with other control methods,the output voltage under adaptive sliding mode control has high voltage stability,providing important guarantees for the safe and stable operation of the energy storage building system.
