An adaptive sliding mode controller (SMC) design with a reinforcement-learning parameter optimization method is proposed for variable-speed trajectory tracking control of underactuated vessels under scenarios involving model uncertainties and external environmental disturbances. First, considering the flexible requirements vessel’s propulsion system, desired navigation speed designed to satisfy an S-curve acceleration deceleration process. The rate change parameters derived. Second, address...
Multiparameter water quality trend prediction technique is one of the important tools for environment management and regulation. This study proposes a new model with better performance, which combined improved sparrow search algorithm (ISSA) support vector regression (SVR) machine. For problems low population diversity easily falling into local optimum (SSA), ISSA proposed to increase initial by introducing Skew-Tent mapping help jump out using adaptive elimination mechanism. The optimal...
As a representative of wide-bandgap semiconductors, wurtzite gallium nitride (GaN) has been widely utilized in high-power devices due to high breakdown voltage and low specific on resistance. Accurate prediction GaN thermal conductivity is prerequisite for designing effective management systems electronic applications. Machine learning driven molecular dynamics simulation offers promising approach predicting the large-scale without requiring predefined parameters. However, these methods...
In the three-dimensional culture model, breeding basket of area is symmetrical and it important to control dissolved oxygen in region improve efficiency. Practical engineering issues, such as influence flow rate, pH, water temperature, biological consumption on content circulating system, must be considered along with presence modeling errors model. The authors propose an adaptive anti-disturbance strategy for that combines nonlinear disturbance observation sliding model control. Initially,...
Single-frame circulation aquaculture belongs to the important category of sustainable agriculture development. In light visual-detection problem related survival rate Portunus in single-frame three-dimensional aquaculture, a fusion recognition algorithm based on YOLOV5, RCN (RefineContourNet) image residual bait ratio, centroid moving distance, and rotation angle was put forward.
