This paper studies the event-triggered control problem of nonlinear discrete-time systems in the presence of external disturbances. In particular, we focus on the case in which whether or not the system state is sampled at step k is determined by the feedback information at step k − 1. This problem is motivated by practical applications, and the proposed solution drastically differs from the existing...
This paper addresses the disturbance rejection problem for a class of linear systems in the presence of input delay via DOBC approach. Truncated predictor feedback method is applied to deal with the input delay based on the estimate of state and external disturbance, and further endeavours are made to ensure the extra integral terms of the system state and external disturbance due to the input delay...
This paper considers the stabilization of a coupled second order ODE-wave system, where the ODE dynamics contain the solution of the wave equation at an intermediate point. We design a stabilizing feedback controller by choosing a suitable target system and backstepping transformation. The backstepping transformation is defined in terms of several kernel functions, for which we establish existence,...
This paper is dedicated to the complete stability analysis of linear fractional order time delay systems (FOTDSs) with commensurate delays of retarded type, inspired by that the complete stability of integer order time delay systems was recently solved within a new frequency-sweeping framework [14]. We are hence motivated to extend the methodology to FOTDSs. The complete stability problem has been...
This paper studies the fixed-time stabilization problem for a class of second-order multivariable multi-input nonlinear systems with matched uncertainties. Different from the control design for scalar systems, a multivariable sliding mode control design, based on a set of nonlinear coupled sliding surfaces, is proposed to stabilize the system at the origin with a uniformly bounded settling time, i...
