基于模糊PID控制的电液力伺服系统的研究

电液伺服控制系统本身具有非线性以及参数不确定性等因素,导致传统的PID控制算法很难使力伺服系统达到满意的控制效果,给系统的控制及仿真造成一定的影响。针对这一问题,基于LabVIEW软件平台研究设计出模糊PID控制算法,并在实际的力伺服控制系统中进行实验验证。结果表明,该控制算法控制精度高且稳定性好,满足控制系统要求。

Research on EIectro-hydrauIic Force Servo ControI System Based on Fuzzy PID ControI

The characters that nonIinearity and parameter uncertainty of EIectro-hydrauIic servo system itseIf,Iead to the traditionaI PID controI aIgorithm is hard to make the force servo system achieve satisfactory controI effect,so affect the controI and simuIation of system.In view of the above contradiction,research of the Fuzzy PID controI based on the LabVIEW2010 soft-ware pIatform,and in the actuaI EIectro-hydrauIic servo system for experimentaI verification.
