Special Issue Information

Dear Colleagues,

Practical processes are usually complex, nonlinear and time-varying. It is generally impossible to obtain an accurate mathematical model due to the uncertainties. It is of vital importance to investigate control problems of nonlinear systems due to their wide existence in the practical world, for example, motion and electrical control systems. For the actual system, it is often necessary to follow some harsh linearization assumptions, which are often inconsistent with the application reality. Moreover, some complex and uncertain control objects cannot be described by the traditional mathematical model, which makes the traditional model-based control methods invalid. There exists the paradox that the actual control task is complex, while the traditional control task has low requirements and cannot do anything about the complexity. To solve the control problems for systems with unknown nonlinearities, intelligent modeling techniques such as fuzzy and neural network modeling methods were introduced.

In recent years, with the rapid development of artificial intelligence, robotics, advanced manufacturing, power systems, aerospace and other fields, traditional control methods are unable to meet the requirements of complex dynamic processes. Therefore, a variety of advanced intelligent control methods such as fuzzy control, data-driven control, neural network control and learning control, have emerged and achieved successful applications. The main aim of this Special Issue is to seek high-quality submissions that highlight emerging theories and applications with advanced nonlinear intelligent control, addressing recent breakthroughs from theoretical and practical aspects.

The topics of interest include, but are not limited to, the following:

  • Fuzzy control;
  • Neural network control;
  • Reinforcement learning;
  • Data-driven control;
  • Modeling approach;
  • Nonlinear intelligent control: theory and applications;
  • Intelligent control algorithms and their applications in power system, robotics, unmanned vehicles, etc.

Autonomous Underwater Vehicles (AUVs), as a member of the unmanned intelligent ocean vehicle group, can replace human beings to complete dangerous tasks in the ocean. It is of great significance to apply reinforcement learning (RL) to AUVs to realize intelligent control. This paper proposes an AUV obstacle avoidance framework based on event-triggered reinforcement learning. Firstly, an environment perception model is designed to judge the relative position relationship between the AUV and all unknown obstacles and known targets. Secondly, considering that the detection range of AUVs is limited, and the proposed method needs to deal with unknown static obstacles and unknown dynamic obstacles at the same time, two different event-triggered mechanisms are designed. Soft actor–critic (SAC) with a non-policy sampling method is used. Then, improved reinforcement learning and the event-triggered mechanism are combined in this paper. Finally, a simulation experiment of the obstacle avoidance task is carried out on the Gazebo simulation platform. Results show that the proposed method can obtain higher rewards and complete tasks successfully. At the same time, the trajectory and the distance between each obstacle confirm that the AUV can reach the target well while maintaining a safe distance from static and dynamic obstacles.
