With the aim of improving rapidity and accuracy quadrotor UAV positional trajectory tracking, this paper proposes a fuzzy automatic disturbance rejection control based on improved whale optimization algorithm (IWOA-Fuzzy-ADRC). (1) To address problems low slow convergence traditional algorithm, combination logistic chaos mapping skew tent is applied to improve diversity initial population. (2) ...

Anti-lock braking system is designed to optimize braking procedure while maintaining automobile steerability through controlling wheels slip. However, due to nonlinearity and uncertainty of ABS structure, designing the controller for wheel slip encounters so many problems which necessitate a robust control system. In this paper, a hybrid controller is proposed for ABS to address this issue. The...
