Abstract and Keywords

Abstract: In order to solve the problems of poor stability and low control precision of conventional proportional integral derivative (PID) controller in unmanned surface vehicle heading control system, a control algorithm combining fuzzy control and back propagation (BP) neural network was proposed. The heading control performance of conventional PID controller, fuzzy PID controller and fuzzy neural network PID controller was compared under the given expected heading angle based on MATLAB. The simulation results show that the fuzzy neural network PID controller has the best heading control performance in unmanned surface vehicle. The above simulation results were further verified by comparing the trajectory and heading angle of unmanned surface vehicle under different heading controllers on the experimental platform.

Keywords: unmanned surface vehicle; heading control; fuzzy control; back propagation(BP) neural network; proportional integral derivative(PID)

摘要和关键词

摘要: 针对常规比例、积分和微分(proportional integral derivative, PID)控制器在无人艇航向控制系统中表现出的稳定性差、控制精度低等问题，文章提出一种将模糊控制与反向传播(back propagation, BP)神经网络相结合的控制算法；在MATLAB中对比常规PID控制器、模糊PID控制器与模糊神经网络PID控制器在给定期望航向角下的航向控制性能，仿真结果表明模糊神经网络PID控制器对无人艇的航向控制性能最佳；在搭建的实验平台上对不同航向控制器下无人艇的航行轨迹和航向角进行比较，实验结果进一步验证了模糊神经网络PID航向控制算法的优越性。
