Design of CNC machining system for ship parts based on improved PID algorithm
Shipbuilding is an important embodiment of national industrial strength.Ship parts processing requires pre-cise 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 ef-fectively 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 flat-ness,contour and machining accuracy of the five-axis numerical control system can meet the design requirements,and the system has good reliability and stability.
