【摘要】 设计了一种"交流发电,直流回馈"电封闭式变速箱加载综合试验台。根据变速箱变载荷加载的要求,提出PI-模糊双闭环加载控制方案,设计了基于误差和误差变化的函数自整定加权因子模糊控制器,还引入虚拟仪器技术对试验台进行自动监控与管理。实践证明,该变速箱加载综合试验台具有操作简便、功能齐全、自动化程度高、易于升级扩展、成本低廉和节能效果显著的特点。更多还原

【Abstract】 This paper designs a new and power-saving electrical power closed loading comprehensive test bench whose characteristic is AC generation and DC feedback.According to the requirement of non-uniform load,the paper puts forward a PI-fuzzy loading project of double closed-loop control,and designs self-adjusting controller based on error and error change.This paper also applies the advanced virtual instrument technology to monitor and manage the test bench automatically.The results indicate that the test bench has the advantages of simple operation,complete function,high-level automation,easily implementing upgrading and expanding,low cost and remarkable energy saving result.更多还原
