Robust NMPC with Disturbance Compensation for Unmanned Surface Vehicle

Autonomous navigation requires an unmanned surface vehicle (USV) to maintain accurate heading and trajectory tracking despite the presence of environmental disturbances. In practice, disturbances such as waves and wind can cause the vessel to deviate from its desired course, reducing navigation accuracy and overall con...

Stability and Optimal Control of a Nonlinear Tourism--Environment Dynamic System for Sustainable Tourism Management

The rapid growth of the tourism sector has generated several challenges, including increased tourist pressure, environmental degradation, and economic imbalances. These challenges can be addressed by developing mathematical models for sustainable tourism. This study develops a nonlinear dynamic model to describe the in...

Numerical solution of the HJB equation using a hybrid Bernstein–fractional Chebyshev spectral collocation method

The Hamilton–Jacobi–Bellman (HJB) equation is fundamental in stochastic optimal control but is often difficult to solve accurately because of its nonlinear and multidimensional structure. This paper develops a hybrid tensor-product spectral collocation method based on shifted Bernstein polynomials in time and fractiona...
