Event-triggered control is an effective strategy, capable of reducing the amount communications and retaining a satisfactory closed-loop performance. In this paper, we aim at proposing event-triggered sampling mechanism studying observer-based output feedback for switched linear neutral systems with mixed time-varying delays. Different from conventional strategies, our proposed one transmits not only state but also switching information to controller, which advantageous in applications where...

Both state‐based and observer‐based output feedback event‐triggered controls for continuous‐time switched linear systems are studied. An improved sampling mechanism is adopted in control, under which Zeno behaviour can be easily excluded process. Meanwhile, it shown that the closed‐loop system stable sense of global uniform boundedness satisfying an average dwell time condition. A numerical example finally given to verify developed results.

Event-triggered control is a strategy, which possesses advantages in applications where communication resources are scarce. In this paper, we study event-triggered for switched delay systems. The proposed triggering condition satisfied only if an error signal exceeds dynamic threshold. Sampler updates and transfers the information of states switching to controller when event triggered, under asynchronous cannot be avoided. We therefore consider systems also. assumed satisfying average dwell...

Cooperative optimisation problems over multi‐agent systems have attracted a lot of attention. Most existing results been developed for the case when cost function is given as summation local utilities. Instead, this study focuses on more general not form or cannot be readily changed into form. The authors call cooperative with inseparable functions. authors’ basic idea to decompose utilities based geometric theory. Each decomposed agent only contains its own variable and constraints,...

Control vector parameterization is a mainstream numerical approach for solving dynamic programming problems. By discretizing the entire time domain into grid of nodes, an infinite-dimensional optimal control problem can be transformed finite-dimensional static optimization problem. Despite attractive advantages high solution accuracy and ease implementation parameterization, rationality partitioning significantly influences efficiency approximating trajectory. In traditional method,...

In this paper, we study model-based event-triggered control (MB-ETC) for a kind of switched discrete-time systems composed stabilizable and unstabilizable subsystems. A nominal dynamic model is constructed at the feedback part so that it can provide an estimate system state input even overall running in open-loop. Since information provided to transmitted over network, mechanism (ETM) taken into account reduce network data transmission. Stability conditions augmented closed-loop are derived...

Control vector parameterization method is the most commonly used numerical computation in solving dynamic programming problems. However, to balance expected trajectory and computational cost, this faces difficulties dividing optimal discretization time grid. In paper, we propose an effective control approach for non-uniform adaptive grid division. By analyzing slope change trend of parameter, nodes are adaptively refined by merging grids with gentle slopes remove unnecessary adding steep...
