| Aim at the problems of control difficulty of GMM intelligent boring bar in boring non-cylinder pin hole, and
based on the existing control system hardware. the software of DSP control system was designed, including A/D
gathering, feedback detection algorithm and programming to realize closed loop control algorithm. On this basis.
experiments to test the overall performance of the control system was carried out. and the actual machining piston pin
hole trajectory tracking experiment was performed by using open loop compensation control of inverse model. the common
PID control and feedforward inverse compensation control methods of PID respectively. The results show that higher
precision can be obtained by using the inverse model feedforward compensation PID control than by using the open-loop
compensation inverse model control for the low frequency processing locus, and the expected technical indicators is
achieved. The established closed loop control system has a very good application effect. |
