摘要
针对电缸直线运动位置误差进行了研究,提出了一种"最小二乘法线性拟合补偿、非线性自适应模糊比例-积分-微分(PID)非线性误差补偿"的复合模式误差补偿方法,重点分析了非线性误差的补偿,建立了电缸测试系统的数学模型并进行了仿真,验证了自适应模糊PID进行补偿的可靠性;结合实验进行了验证,证明了该方法具有很好的可行性,取得了理想的效果。
Aiming at position error of linear motion of a type of electric cylinder, a composite patterns error compensation method of ＂least squares linear fitting compensation, nonlinear adaptive fuzzy PID of nonlinear error compensation＂ is proposed, specially analyze on nonlinear error compensation and mathematical model for electric cylinder test system is established and simulated to prove the reliability of the adaptive fuzzy PID compensation.. It is combined with the experiment to verify and it is proved that the method is feasible and ideal effect is obtained.
