Firstly, the linear path-following guidance law is developed by line of sight and Serret-Frenet frame. Then, the path-following controller is designed based on the nonsingular terminal sliding mode, which can stabilize the path-following errors. Furthermore, the PSO is introduced to optimize the controller parameters in order to obtain better control performance. Finally, the numerical simulation results show that the designed controller can accurately execute the horizontal straight path following in finite time, and can effectively overcome the influence of constant unknown current and model parameter perturbations. %U http://www.co-journal.com/EN/10.12382/bgxb.2021.0491
