This paper presents a novel approach for designing a composite controller that finite time simultaneously stabilizes two single input nonlinear Port-Controlled Hamiltonian (PCH) systems under disturbances. Firstly, using a single output feedback, two PCH systems are combined to generate an augmented PCH system based on the Hamiltonian structure properties. Then, a finite time disturbance observer...
In this paper, the finite-time output feedback stabilization problem for a kind of second-order system with mismatched disturbances is investigated. To estimate both the unknown states and the disturbances in such a system, a finite-time convergent observer is designed. Based on homogeneous control technique and the designed observer, an output feedback composite controller is proposed. The developed...
In this technical note, the dynamical behaviors of discrete-time terminal sliding mode control systems based on Euler's discretization is investigated. Based on a recursive analysis, the boundedness for the steady states of the system is established. Theoretical analysis shows that the discrete-time terminal sliding mode control method can offer a higher output tracking precision than the discrete-time...
