摘要
针对非对称液压缸系统,将数学推导的方法与以PRMS信号为激励信号的最小二乘法辨识法相结合,建立了非对称液压缸系统的数学模型。通过对比研究仿真结果和系统的实际输出,调整了系统模型参数,最终结果验证了该非对称模型的正确性和可用性,同时也说明了辨识方法的正确性。
Aiming to non-symmetrical hydraulic servo-system, math deducibility method and least square method which used PRMS signal as excite signal, were proposed to obtain the mathematic model of this non-symmetrical hydraulic servo-system. Comparing the emulation result with output of the actual system, the parameters of identification model were revised. The final experiment results validate the correctness and useability of this model, and also prove the validity of identification method.
