摘要
为了提高立式加工水基切削控制精度,提出基于模拟退火的立式加工水基切削精度自适应控制方法。首先建立立式加工水基切削数学模型;其次设计了立式加工水基切削系统PID控制器;最后基于模拟退火方法对PID控制器进行参数优化,实现立式加工水基切削精度的自适应控制。测试结果表明:所提方法在0.25 s即完成控制动态响应;在阻尼系数、转轴加速度、进给量发生改变时,仍能保持切削力稳定,鲁棒性较强;噪声干扰下切削力偏差值小于45.3 N,切削自适应控制精度较高。
In order to improve the accuracy of water-based cutting control in vertical machining,a simulated annealing based adaptive control method for water-based cutting accuracy in vertical machining is proposed.It establishes a vertical machining water-based cutting mathematical model,designs a PID controller to control the vertical machining water-based cutting system.Then based on the simulated annealing method,the parameters of the PID controller are optimized to achieve adaptive control of water-based cutting accuracy in vertical machining.The test results indicate that the proposed method completes the control dynamic response within 0.25 seconds;When the damping coefficient,shaft acceleration,and feed amount change,it can still maintain stable cutting force and strong robustness;The deviation value of cutting force under noise interference is less than 45.3 N,indicating a high accuracy of cutting adaptive control.
