Simulation of high precision angle control in mechanical manufacturing Numerical Control Technology

摘要

during the study process high precision angle control in the mechanical manufacturing computer numerical control (CNC) technology, using the current algorithm to control the high precision angle of mechanical manufacturing is unable to realize the smoothing angle control, and angle control error is large. For this purpose, a high precision angle control method based on the improved PID fuzzy algorithm is proposed for mechanical manufacturing CNC technology. With the method, the angle detection system detects the signal and sends to the microcontroller, technology processing like scale conversion, digital filtering are followed in microcontroller. The treated measurement value and set value are compared, through digital PID computing to input digital control signal. On the basis of this, single input and single output nonlinear system equations of angle control are built to design an angle feedback controller based on fuzzy logical, the output of the system in a certain extent tracks and approaches ideal angle output of high precision, and complete high precision angle control in the machinery manufacturing CNC technology effectively. The experimental results show that the accuracy of high precision angle control method based on the improved PID fuzzy algorithm in mechanical manufacturing CNC technology is high, and the robustness is strong.
