摘要
在研究了某导弹电动舵机系统的结构特点与数学模型的基础上,结合人工免疫原理与切换控制技术,提出了免疫切换跟踪控制器,给出了控制器的设计方法。实验与仿真结果表明所设计的免疫切换跟踪控制器对导弹电动舵机系统中的饱和非线性有很强的鲁棒性,同时能有效降低常规切换控制所产生的抖振,改善动态品质,提高导弹的位置跟踪性能。
Structural characteristics and mathematical model of a missile electromechanical actuator system were researched deeply. Combined artificial immune principle with switching control technology, an immune switch tracking controller was proposed and the controller design method was given. Experimental and simulation results demonstrated the controller had strong robustness to the saturation nonlinear and decreased the chattering phenomenon and improved dynamic quality effectively.
