摘要：Controllability of complex networks through pinning control toward a desired trajectory is crucial for ensuring synchronization stability. Concerned with the local stability of the network's synchronization, here, the controllability problem is addressed different from the literature by incorporating weighted Laplacian and nonuniform feedback gain. This approach has led to a spectral radius minimization problem, where using its semidefinite programming (SDP) formulation leads to a unique optim...

摘要：This article provides a new method for trajectory tracking for quadcopters following a cascaded control approach with formal closed-loop tracking guarantees. An outer-loop model predictive controller generates twice differentiable acceleration references, which provide attitude, angular velocity, and acceleration references for a nonlinear inner-loop controller. The model predictive controller allows for tracking of references while explicitly considering that the thrust of the quadcopter is u...

摘要：The aim of this article is to provide a new linear matrix inequality (LMI)-based robust multivariable super-twisting algorithm design able to deal with convex bounded model uncertainties in the input matrix and exogenous disturbances with norm-bounded time derivative. The final state feedback gain is calculated from a convex programming problem, expressed by LMIs with respect to all involved variables, that optimizes a guaranteed (worst case) performance index associated to the closed-loop sys...

摘要：In this article, we investigate the continuous and sampled-data safety-critical control problems with control barrier functions in the presence of time-varying disturbances. To this end, a nonlinear disturbance observer is first designed to estimate the disturbance, and the continuous safe control design of the nominal systems is formulated as a quadratic program. We then design a continuous composite controller by integrating the disturbance compensation term and the state feedback term compu...

摘要：In this article, the robust distributed optimal coordination (DOC) problem over unbalanced directed communication networks is investigated for heterogeneous multiagent systems subjected to external disturbances. First, by introducing an external disturbance observer, a balanced compensation variable and using the output regulation technique, a new robust continuous-time DOC algorithm is developed, ensuring that the sum of the local convex objective functions is optimal and the behaviors of all...

摘要：A Pareto-improving incentive mechanism to improve the weighted social welfare and achieve continual Pareto improvement for a pseudogradient-based noncooperative dynamical system is developed. In the proposed approach, the system manager remodels agents' dynamical decision-making by collecting taxes from some agents and giving some of the collected taxes to other agents as subsidies with a sustainable budget constraint. Sufficient conditions are derived under which agents' state converges towar...

摘要：In this article, we study the finite-time distributed resilient tracking control problem for nonlinear multiagent systems under denial-of-service (DoS) attacks. To solve the problem, a new hierarchical control method is proposed, which includes a resilient distributed observation layer, a local performance improvement layer, and a decentralized tracking layer. Specifically, a novel model transformation method is first introduced in the resilient distributed observation layer to transform the r...

摘要：In this note, we discuss a generalization of the well-known implicit function theorem to the time-delay case. We show that the latter problem is closely related to the bicausal changes of coordinates of time-delay systems [Califano and Moog (2014), Califano and Moog (2017)]. An iterative algorithm is proposed to check the conditions and to construct the desired bicausal change of coordinates for the proposed implicit function theorem. Moreover, we show that our results can be applied to delaye...

摘要：A new zero-order algorithm to solve the maximum hands-off control is proposed. Maximum hands-off control is discretized into a convex linear programming problem by zero-order-hold discretization. The first-order necessary conditions for linear programming problems are presented. To ensure that the switching points meet the allowable error, the jump function is used to preliminarily determine the switching points of the control variable. The finite switch number lemma for the maximum hands-off ...

摘要：This article considers the adaptive fixed-time control problem for high-order nonlinear systems in the presence of unknown control coefficients and quantized input. Unlike the previous results, the bounds of the control coefficients and the knowledge of the quantizer parameters are not required to be known. By utilizing adding a power integrator method, an adaptive controller is designed where a tuning parameter is introduced to compensate the unknown system parameters. By using the fixed-time...
