基于免疫原理的气动比例阀缸系统的位置控制

Pneumatic Proportional Valve-cylinder Position Control System Based on Immune Feedback Principle

借鉴生物免疫反馈应答机理,基于抗原、T细胞以及B细胞间的浓度关系数学模型,设计了一种新型免疫控制器用于气动比例阀缸系统的位置控制。仿真结果表明,对于被控对象本身的非线性、时变性、参数变化大和负载干扰大的特征,所设计的免疫控制器相对于模糊控制器具有较好的动态特性和跟踪特性,且具有较好的自适应能力。

Motivated by biological immune feedback theory,based on the density math model of antigen, T cell and B cell,a novel immune feedback controller was derived for pneumatic proportional valve-cylinder posi- tion control system. This kind of system has the characteristics of nonlinear, time dependence, wide range of parameter change and large outer load interference. The simulation results show the better tracking character- istics and adaptability of the proposed controller compared to fuzzy controllers.
