摘要
针对传统数控系统的封闭式结构及无法实现自主实时获得最佳切削参数的问题,设计并开发了一个模块化的、能实现基于约束控制的、加工参数可在线调整的自适应开放式智能控制器。构建了该控制器中自适应控制技术的实现体系,通过建立自适应约束控制与插补控制之间的有限状态机任务模型,解决了两者之间指令的有效融合及同步问题。基于切削力为约束的模糊自适应控制器进行的实际切削试验表明了所建集成式智能自适应控制体系的可行性和有效性。
Aiming at the problems of traditional closed structure of Computer Numberical Control（CNC） and the real-time optimal cutting parameters couldn＇t be obtained automatically,a self-adaptive open intelligent controller was designed and developed,which was modularity and could realize online adjustment based on constrained goals and machining parameters.Architecture of the open intelligent controller was established.Through setting up finite state machine model between adaptive constrained control and interpolation control,problems of effective fusion and synchronization between them were solved.Practical milling experiments of fuzzy adaptive controller based on cutting force as the constrained verified the integrate intelligent adaptive control system＇s feasibility and validity.
