Design on a pulsed wire feeding control system of all - position narrow gap and thick - walled pipe welding 厚壁管窄间隙全位置焊接脉动送丝系统设计
In this paper , according to the technological requirement of machining optical parts and the principle of locus shaping technique , the author devised a special set of feed control system 本文根据光学零件加工的工艺要求和轨迹成形法加工的原理,设计出一套专门的微量进给控制系统。
The method can eliminate the conventional fuzzy control system ' s steady - state errors and flutters . and , the method of forward feed control is used to reduce the tracing errors during glide slope phase 在此基础上,采用带优化修正函数无量化的模糊控制方法,设计飞机的微波着陆控制系统,并进行了闭环仿真。
Based on the analysis of characteristics , quintic splines are considered as the best spline functions that can commendably satisfy the requirements of hsc of surfaces . so the generation and processing of quintic spline - based nc instructions , which includes the generating process of nc instructions , processing of geometrical data , feed control and real - time interpolation , are investigated , and the theory , method and technique are systemically founded 因此,对基于五次多项式样条的cnc系统通用的nc指令生成与处理技术进行了系统研究,包括基于五次样条的指令生成过程、几何数据处理、速度控制和实时插补技术等,系统地建立了一套比较完整的基于五次样条的cnc理论与方法体系。
An on - line tuning parameter of proportional integral derivatives ( pid ) controller base on expert knowledge is presented in this paper , moreover the paper introduces differential forward feed control commonly used in simulators to speed up frequency response . to compensate torque interruption , the author designs a compound control strategy 在数学模型上,仿真研究了基于专家知识的在线变参数pid控制策略、输入信号微分前馈的复合控制策略以及转矩干扰的补偿控制策略,并将这些控制策略的效果进行了对比研究。
