摘要
船舶制造是国家工业实力的重要体现,船舶零件加工需要电机精确定位,但传统PID算法存在超调以及稳定时间过长的问题,因而难以满足现代造船业的需要。本文将PID算法和模糊控制进行有效结合,分析改进PID算法的基本原理,并对改进的PID算法进行建模和仿真。在此基础上提出船舶五轴零件数控加工系统的设计目标,并设计硬件的整体结构框架。测试结果表明,五轴数控系统的加工平面度、轮廓度以及加工精度均能够满足设计要求,系统具有较好的可靠性和稳定性。
Shipbuilding is an important embodiment of national industrial strength.Ship parts processing requires precise positioning of the motor.However,the traditional PID algorithm has the problems of overshoot and long stability time,so it is difficult to meet the needs of modern shipbuilding industry.In this paper,the PID algorithm and fuzzy control are effectively combined,the basic principle of the improved PID algorithm is analyzed,and the improved PID algorithm is modeled and simulated.On this basis,the design goal of the numerical control machining system for ship five-axis parts is put forward,and the overall structure framework of the hardware is designed.The test results show that the machining flatness,contour and machining accuracy of the five-axis numerical control system can meet the design requirements,and the system has good reliability and stability.
