摘　　要：提出了针对多种肥料自动配比变量施肥的技术方案。机械结构方面设计了多个独立的料箱,每个料箱均能够独立被微控制器控制;肥料流量控制则是根据肥料流量以及施肥机械的行走速度,采用了基于模糊免疫PID算法对伺服电机进行控制;在算法性能方面,采用Mat Lab软件对模糊免疫PID算法和传统PID算法做了比较,证明了算法的鲁棒性和稳定性;最后,设计田间作业实验方案,通过实验数据证明了该变量施肥系统施肥精度高、可重复性好。Servo system is the most important part of variable fertilization which the motor position accurate control is the key. In view of contradiction between rapidity and stationary existed in the variable fertilization progress of conventional PID control algorithm. In this paper, an fuzzy immune PID controller which increases the fuzzy immune feedback process-ing module compare with traditional PID controller. Finally, the adaptively adopt accurate control was finished on the mo-tor position of servo system. The results show this new controller has many advantages such as fast response speed, strong adaptability, high controlled control precision.
