Most of the existing results on anti-disturbance consensus control of multi-agent systems focus on matched-disturbance rejection and the disturbances are assumed to be constant or slowly time-varying. This paper investigates the consensus control problem of double-integrator multi-agent systems with mismatched disturbances, which can be some kinds of faster time-varying disturbances, such as ramp...
In this paper, the finite-time consensus problem is investigated for leader-follower second-order multi-agent systems subject to mismatched disturbances. This control problem is solved via a feedforward-feedback composite control scheme, which is composed of the non-singular terminal sliding-mode control (NTSMC) and disturbance observer based control (DOBC) methods. In the first step, for each follower,...
In this paper, consensus disturbance rejection control problem for a class of second-order leader-follower multi-agent systems are investigated. Such systems not only contain unmeasurable states but also suffer from mismatched disturbances. By combining integral-type nonsingular terminal sliding-mode control technique and an extended-state observer technique together, finite-time consensus is achieved...
In this paper, the consensus control problem is investigated for second-order multi-agent systems encompassing mismatched disturbances. By integrating both sliding-mode control (SMC) and disturbance observer based control (DOBC) approaches together, a composite consensus control strategy is proposed. In the first step, for each agent, a nonlinear disturbance observer is developed to estimate its mismatched/matched...
This paper addresses the problem of finite-time consensus for multi-agent systems with high-order dynamics. Based on the adding a power integrator technique and the neighbor-based rule, a class of distributed high-order finite-time consensus algorithms are explicitly constructed. Under the proposed finite-time control law, it is shown that the states consensus can be achieved in a finite time. An...
