摘要 VACA是变尺度算法融入蚁群优化算法中而形成的一种混合算法。针对电液比例系统PID控制参数整定问题,提出了基于改进蚁群算法的PID参数优化方案,并给出了具体的实现步骤:建立臂架电液控制系统的数学模型,利用Simulink工具箱建立了电液比例控制系统的VACA-PID的仿真模型,进行了仿真和验证。结果表明:VACA-PID控制器具有良好的静、动态性能,完全能达到电液比例控制系统的要求。 VACA is a hybrid algorithm combined with the variable metric algorithm and ant colony optimization algorithm.For the electro-hydraulic proportional control system for PID parameter tuning problem,this paper puts forward the optimization of PID parameters based on VACA,and gives the specific implementation steps：establish mathematical model for electro-hydraulic con-trol system,establish the simulation model of electro-hydraulic proportional control system of VA-CA-PID by using SIMULINK toolbox,simulation and verification.The results show that：the VA-CA-PID control er has good static and dynamic performance,can ful y meet the electro-hydraulic proportional control system.
