摘要
为了解决微织构机床速度伺服跟踪精度不高的问题,在建立机电耦合动力学模型基础上,提出结合改进人群搜索优化算法(Improved Seeker Optimization Algorithm,ISOA)与前馈补偿PID的控制方案,设计了ISOA+前馈补偿PID控制器的控制结构,实现微织构机床伺服进给系统的PID参数寻优设计.为验证该控制策略的实际效果,采用Matlab搭建仿真实验平台,并与传统的智能优化算法相比较.仿真结果表明,基于ISOA优化的前馈补偿PID优化效果更好,速度跟踪性能得到很大改善,验证了其正确有效性.
Abstract
To further improve the micro texture position tracking precision machine tools,the establishment of ball screw mechani-cal transmission model and dynamic model design of servo control system based on model error compensation scheme for the de-sign of the control system,puts forward a search algorithm based on improved crowd feedforward PID control strategy,estab-lished the ISOA-PID controller of the control structure,completed the design of PID parameter.Matlab is used to build a simula-tion experiment platform.In order to verify the actual effect of the control strategy,Matlab was used to build a simulation experi-ment platform and compared with the traditional intelligent optimization algorithm.The simulation results show that the feedfor-ward compensation PID optimization effect based on ISOA optimization is better,and the speed tracking performance is greatly improved,which verifies its correctness and effectiveness.
