摘要
位置扰动型施力系统存在着多余力的问题，同时由于系统的非线性及参数时变等因素的影响，给系统的校正和优化带来了困难．为了消除位置扰动型施力系统中存在的多余力以及非线性、参数时变等因素的影响，采用在非线性前馈校正基础上的模糊自适应控制策略，可以较好地消除系统的多余力，同时克服系统的非线性及参数时变等因素的影响，改善系统的动态品质．
There is a problem of extraneous force in position disturbance type of loading servo system, and because of the system's non linearity and variation of parameters, it is difficult to correct and optimize. A adaptive fuzzy control approach is developed on the base of non linear feedforward control to eliminate extraneous force and affects of the system's non linearity and variation of parameters. The effectiveness of eliminating extraneous force and improving dynamic performance is illustrated through simulation studies. Above conclusions from position disturbance type of loading servo system can also be extended to inner force disturbance type of loading servo system.
