predefined time预定的是收敛的时间上界而prescribed time预定的直接是收敛时间。
In this paper, the predefined-time control problem with prescribed performance is investigated for bilateral teleoperation systems with a single master and multiple slaves. The difficulty lies in the realization of predefined time stability and synchronization control of single-master and multi-slave ...
A predefined-time (PT) tracking adaptive control method is studied for non-affine pure-feedback nonlinear systems, with an emphasis on its practical application in robotic exoskeleton technology. A novel PT neural networks control algorithm is implemented, by leveraging the approximation capabilities of...
Predefined-time bipartite containment control of multi-agent systems with novel super-twisting extended state observer study addresses the bipartite containment control of multi-agent systems with predefined-time convergence. First, a predefined-time distributed observer (P... ChangShaoping,WangCanfeng,Luo...
This notion is related to the posicast control given in [25], [28] and the fixed terminal point regulator problem presented in [21]. Predefined-time controllers have been proposed for first-order systems [23]. Recently, some works extended these results to the case of second-order systems....
This paper investigates the predefined-time control problem for a class of nonlinear systems subject to unmatched parametric uncertainties and asymmetric output constraints. A finite-gain based adaptive control scheme is proposed, with which the system is regulated to the equilibrium within the prescribed...
over several control strategies like backstepping control [25], adaptive control [26], saturation control [27], PID control [28], etc. Further studies onSMCcan be found in [29], [30]. The implementation ofSMCconsists of two parts. The first is to design a sliding manifold that specifies...
Introducing an excessive number of control parameters can, paradoxically, detract from controller performance. The concept of predefined time stability, which dictates the maximum allowable system convergence time to meet specific task demands, has recently gained traction in control method research. Juan ...
It is well‐known that the finite‐time and the fixed‐time control can ensure the finite‐time and the fixed‐time stabilities of systems, respectively. Therein the finite convergence time depends on both the initial conditions of systems and the controller design parameters, and the fixed conver...
In this brief, we propose a control method for high-order integrator systems that achieves predefined-time convergence, i.e., the system is driven to the origin in a desired settling time that can be set as an explicit parameter of the controller and it is achieved independently of the init...
