【摘要】 阀控非对称液压缸电液伺服系统是本质非线性的,液压缸正反两个方向的动态特性不一致,为了改善系统的动态性 能,本文根据液压缸活塞杆的不同运动方向分别给出了相应的三维模糊控制器来控制该系统,实验表明这种方法不仅有效地解 决了系统的不对称性,而且改善了系统的动态性能。更多还原

【Abstract】 Valve-controlled asymmetrical cylinder servo system are essentially nonlinear and asymmetrical, and the dynamic properties in the two directions of the cylinder are not uniform. In this paper, three-dimensinal fuzzy controller is featured to control this kind of system, respective to the two directions. Experiments show that it can effectively solve the asymmetry of the system and improve its dynamic property.更多还原
