In this paper, the output containment control problem of heterogeneous linear multi-agent systems is investigated. The objective of the output containment control problem is to make a group of agents converge to a convex hull spanned by some leaders. A distributed control law based on output regulation framework is proposed, where a distributed observer is designed in the control law for agents estimating...
This paper deals with node-to-node consensus tracking problem for multi-agent systems (MASs) with linear dynamics and directed switching topologies. The coordination goal in the present framework is to employ some distributed control laws such that each follower can track its corresponding leader. Unlike most existing works where the relative full state information of neighboring agents are utilized,...
The fixed-time synchronization problem fsor a class of second-order nonlinear multi-agent systems with a leader-follower architecture is investigated in this paper. To achieve the fixed-time tracking, the design procedure is divided into two steps. At the first step, a distributed fixed-time estimator is designed for each agent to estimate the leader's state in a fixed time. Then, at the second step,...
A sliding mode control (SMC) strategy is presented for a quadrotor-based hover system, which achieves asymptotic attitude regulation in the presence of electrical and physical constraints. A sliding mode observer is employed to estimate the angular velocities. In addition, the proposed control design incorporates the input voltage constraints inherent in practical systems. A rigorous Lyapunov-based...
The linear time invariant (LTI) observer-based discrete-time sliding-mode control problem is considered for a robust tracking of higher-order dynamic delay-time systems. Here, Luenberger observer is used for estimation of system states as all states are not available for measurement. Sliding surface is selected based on output feedback and observer states to realize the sliding-mode control. Observer...
In this paper, the adaptive consensus disturbance rejection problem is considered for the liner multi-agent systems under directed graphs. Based on the relative state information of the neighboring agents, the consensus protocols, including a state observer and a disturbance observer, are designed to guarantee that the consensus error goes to zero with the complete disturbance rejection. Furthermore,...
This paper addresses adaptive synchronization control problem of networked robot systems characterized by Lagrangian function, where exact dynamic models are unknown and velocity measurements are unavailable. A class of distributed observers, comprised of multiple dynamic variables and static variables, are established based on not imposing a priori restriction on the boundness of the observer states...
In this paper, linear active disturbance rejection control (LADRC) is investigated for the load frequency control (LFC) systems with wind turbine. The wind power is considered as a stochastic load to the power grid. To compensate the stochastic disturbance with LADRC, we adopt a two-stage design method. First an LQG controller is designed to handle the stochastic nature of the load, then the intrinsic...
