摘要
针对电液伺服力控系统的大惯性、大滞后和高阶非线性、不确定性的特点,结合无模型自适应控制(MFAC)对大惯性、大延迟适应性和模糊控制适应性强的优点,设计了模糊无模型控制器;并采用DSPACE对该控制系统进行了半实物仿真研究。仿真结果表明,相比于基本无模型控制,模糊无模型控制器计算量小、响应速度快;并能够很好地消除试件上的输出误差,提高输出力的的精度,使系统具有较好的适应性。
As for the features of large inertia, large delay, non-linear, uncertainty of the electro-hydraulic servo force control system, combining the advantages of adaptability to inertia and delay of the model-free adaptive controller （MFAC） and strong adaptability of fuzzy controller, a Fuzzy-MFAC has been designed and semi-physical simulation has been adopted by DSPACE. Results show that compared with basic MFAC, the Fuzzy-MFAC have a little amount of calculation and rapid response speed, and it can eliminate the output error of the specimen, improve the accuracy of the output power and make a better adaptability for the system.
