摘要: 目前,广泛应用于金属板材精密折弯作业的折弯机送料系统普遍采用比例、积分、微分(Proportional、Integral、Differential,PID)控制,该方法存在参数调节困难和适应能力差等问题。针对此类问题,设计一种双模态粒子群优化(Particle Swarm Optimization,PSO)算法,首先分别与标准PSO算法、线性递减PSO算法进行对比,其收敛速度分别提升了43.7 %、19 %;然后将双模态PSO算法与PID控制结合,通过迭代寻优优化的PID参数,有效解决了PID控制的参数调节难题。在MATLAB/Simulink软件中对优化前后算法进行仿真分析,结果表明:双模态PSO优化PID参数的方法相比于优化前PID具有响应速度快、超调量小的优点,提高了折弯机送料系统适应系统状态变化的能力。

Abstract: Currently, in the precise bending operations of metal sheet fabrication, the feed system of bending machines predominantly employs PID control algorithms. However, these algorithms often encounter challenges such as difficult parameter tuning and limited adaptability. To address these issues, a dual-modal Particle Swarm Optimization (PSO) algorithm was designed. Comparative analysis with standard PSO and linearly decreasing PSO demonstrated convergence speed improvements of 43.7 % and 19 %, respectively. Subsequently, the PSO algorithm was integrated with the PID controller to iteratively optimize and determine the PID parameters, effectively overcoming the parameter adjustment difficulty inherent in traditional PID algorithms. MATLAB/Simulink simulations of both approaches indicated that the dual-modal PSO-optimized PID method offers faster response times and reduced overshoot compared to conventional PID, thereby enhancing the feed system's ability to adapt to variations in system operational states.

Key words: bending machine feeding system, PID control, improve Particle Swarm Optimization (PSO) algorithm, Simulink simulation
