Adaptive Navigating Control Based on the Parallel Action-Network ADHDP Method for Unmanned Surface Vessel

Abstract

The feedback PID method was mainly used for the navigating control of an unmanned surface vessel (USV). However, when the intelligent control era is coming now, the USV can be navigated more effectively. According to the USV character in its navigating control, this paper presents a parallel action-network ADHDP method. This method connects an adaptive controller parallel to the action network of the ADHDP. The adaptive controller adopts a RBF neural network approximation based on the Lyapunov stability analysis to ensure the system stability. The simulation results show that the parallel action-network ADHDP method has an adaptive control character and can navigate the USV more accurately and rapidly. In addition, this method can also eliminate the overshoot of the ADHDP controller when navigating the USV in various situations. Therefore, the adaptive stability design can greatly improve the navigating control and effectively overcome the ADHDP algorithm limitation. Thus, this adaptive control can be one of the intelligent ADHDP control methods. Furthermore, this method will be a foundation for the development of an intelligent USV controller.

“…Chen used an ADP algorithm to optimize the online parameters of the GH4169 superalloy thermal deformation process [22], obtaining a more uniform and finer microstructure. Huang proposed an ADP controller based on Lyapunov to realize more accurate and faster navigation of unmanned surface vessels [23]. Ruan designed an optimal online-learning fin-stabilizer controller based on ADP [24], which reduced the error of the ship roll model and the influence of external disturbances.…”

Comparison of Linear and Nonlinear Model Predictive Control in Path Following of Underactuated Unmanned Surface Vehicles

“…The first category comprises innovative control algorithms proposed in recent years, and these can be further divided into two types. The first type consists of advanced adaptive control algorithms [6][7][8]. These algorithms typically involve the fusion of multiple technologies to better address the uncertainties encountered and enhance path following accuracy.…”
