基于 RBF 的电液变量施肥控制系统 PID 参数整定
PID Parameter Setting of Electro-hydraulic Variable Rate Fertilization System Based on RBF
摘要
Abstract
Nonlinearity of electro-hydraulic variable rate fertilization system and limitations of PID algorithm lead that normal PID control cannot meet the performance requirements of control system .Aimed at this , a method of setting PID parameter based on RBF neural network has been proposed , which takes advantage of adaptive radial basis function neu-ral network ( ARBFNN) to identify the Jacobian information of controlled object , adopts gradient descent to calculate PID parameters Δkp ,Δki ,Δkd ,and conducts incremental PID control on system .Compared with the step response curves of incremental PID algorithms , it can be learnt that the system which adopts RBF-PID algorithm has excellent dynamic per-formance and strong adaptivity .关键词
