GA-RBF Neural Network Control for Trajectory Tracking of Multilink Robot Arm
摘要
Abstract
A new closed loop adaptive control system of GA-RBF neural network is designed to solve the problem of incomplete information and external disturbance of multilink robot arm model system.The system uses radial basis function (RBF) neural network to approximate and compensate the system model errors and external disturbance.Based on the computed torque method of manipulator,it realizes trajectory tracking control;based on genetic algorithm (GA) and the online optimization of RBF network weights,it ensures that the manipulator control system can get stable in a shorter period of time,to achieve high precision tracking trajectory,and improves the performance of trajectory tracking.The effectiveness of the proposed method is verified by the results of MATLAB simulation.关键词
