Fixed-time ESO based fixed-time integral terminal sliding mode controller design for a missile
ISA Transactions, 2022This paper studies a novel fixed-time extended state observer based fixed-time integral terminal sliding mode controller for partial integrated guidance and control design. Firstly, a class of arbitrary-order systems with fixed-time stability is proposed by utilizing homogeneous approach, whose upper bound of convergence time is given.

Fixed-time control of competitive complex networks
Neural Computing and Applications, 2021This paper aims to establish several synchronization criteria of competitive complex networks (CCNs) by using fixed-time (FDT) control. In CCNs, the variations of different nodes are diverse if they are influenced by external environment. Here, we design two types of controller to deal with the different variations of nodes.

Fixed-time attitude tracking control for spacecraft based on a fixed-time extended state observer
Science China Information Sciences, 2021This paper deals with the problem of fixed-time attitude tracking control for spacecraft subject to model uncertainties and external disturbances. Firstly, by using a fixed-time extended state observer (FxTESO), the synthetic uncertainties generated by external disturbances and model deviations can be estimated and compensated accordingly. We propose a

Neural Processing Letters, 2021
In this paper, we emphasize on a novel fast fixed-time control strategy and its application to fixed-time synchronization control of semi-Markov jump delayed Cohen-Grossberg neural networks (SMJDCGNNs). First, we consider a class of SMJDCGNNs. Second, a novel fast fixed-time control strategy is proposed and designed to control the considered delayed ...

Fixed-Time-Synchronized Consensus Control of Multiagent Systems
IEEE Transactions on Control of Network Systems, 2021In this article, a unique multiagent control problem is defined—all the elements of all the agent states reaching consensus at the same time, i.e., the multiagent system achieves time-synchronized consensus and fixed-time-synchronized consensus, where the upper bound of the synchronized settling time is independent of the initial states of multiagent ...

Fixed-Time Quasi-Containment Control with Antagonistic Nodes
2019 IEEE 15th International Conference on Control and Automation (ICCA), 2019This paper investigates the fixed-time quasi-containment control problem of networked multi-agent systems in the presence of antagonistic nodes. Multiple agents are nominated as the leaders, while the remaining agents are the followers. Among the leaders, some of them disseminate not the real state but an opposite one described by scaling parameters. A

2020 5th International Conference on Automation, Control and Robotics Engineering (CACRE), 2020
This paper proposes a novel fixed-time control scheme for trajectory tracking of marine surface vessels (MSVs). A fixed-time disturbance observer (FDO) is introduced to improve the robustness. Taking advantage of the FDO, a fixed-time adding a power integrator (FAPI) control law is employed to trajectory tracking control design. The proposed scheme can

Adaptive fixed-time control for Lorenz systems
Nonlinear Dynamics, 2020This paper focuses on the problem of fixed-time chaos suppression and stabilization of a class of Lorenz systems with uncertain parameters. Based on the fixed-time stability theory, adaptive control and backstepping algorithm, a novel adaptive practical fixed-time controller is proposed.

Continuous fixed-time controller for stabilizing an armature-controlled DC motor
2017 IEEE 26th International Symposium on Industrial Electronics (ISIE), 2017This paper presents a continuous fixed-time observer-based controller driving all states of an n-dimensional chain of integrators to the origin for a finite pre-established (fixed) time using a scalar input, when only the highest relative degree state can be measured.
