摘要
由于电液伺服振动台具有很强的非线性和时变性,采用传统PID算法控制时往往存在较大误差,难以得到期望输出。现在传统PID算法的基础上加入迭代学习算法,仿真结果表明该方法可以很好地消除输出误差,在选择合适算法参数的前提下,可以精确实现期望的输出轨迹。
The electro-hydraulic servo shaking table is a highly nonlinear and time-varying system,so the expected output usually cannot be obtained when only the traditional PID controller is used.Then the iterative learning control arithmetic is applied to the control of thesystem.Simulation result demonstrates that the output error can be eliminated appropriately when this method is used.If the control parameters are set properly,the system can output the desired curve accurately.
