In this paper, a novel technique of second order recursive reaching law based sliding mode control for a discrete-time system is presented. The proposed second order recurrence dictates the dynamics of sliding function using its two past terms. The synthesized control input utilises two past control inputs and results in better continuity in discrete-time, known as (p,q)-continuity.

The camera stabilizer stabilizes the camera’s line of sight by isolating the camera from the model uncertainties, disturbances of operating environment and system movements. This paper presents a voltage-base optimal adaptive fuzzy sliding mode control for camera stabilizer. In this proposed control method, a voltage-base sliding mode controller is applied. But unfortunately, undesirable ...

The formation control of unmanned surface vehicles (USVs) while considering communication topology, dynamic model uncertainties, environmental disturbances, and a fast convergence rate is addressed in this paper. First, graph theory introduced to describe the connective relationships establish generalized errors among USVs. Then, second-order nonsingular terminal sliding-mode (SOFNTSMC) designe...
