In practice, the time-varying communication delays and actuator failures are main inevitable issues in nonlinear multilateral teleoperation systems, which can reduce performance stability of considered systems. This article proposed a novel failure-distribution-dependent H∞ fuzzy fault-tolerant control scheme to realize position synchronization force tracking simultaneously for Firstly, systems were modeled as kind T-S with multiple delays. Then, based on distribution characteristic...
In this paper, the event-triggered control problem is investigated using backstepping techniques for nonlinear systems with dead-zone input. The external disturbance and unknown parameters are also considered in controller’s design. It well known that errors input signal measurements inevitable. control, such will directly affect whether updated. This measurement error can be seen form of interference to threshold. Therefore, unlike traditional existence threshold proposed controller not...
Abstract It is well known that unknown modeling errors cannot be avoided in practice. Such unmeasured uncertainties are usually denoted as nonlinear functions exist every channel of the system equation. This paper aims to develop an output feedback adaptive control scheme by constructing state estimation filters address such errors. In controller design, these caused will accumulated last step for compensation. Unknown parameters existing upper bound and estimated synchronously based on...
Abstract The trajectory tracking control for wheeled mobile robots (WMRs) with unknown longitudinal slipping is studied in this paper. Firstly, the ratios are introduced to describe slippage and kinematic model of WMRs established, which takes displacement between center mass WMR midpoint driving wheels axis into consideration. Then an adaptive law proposed based on a new Lyapunov function, asymptotic stability error system derived directly by Barbalat's lemma. Finally, some numerical...
This article focuses on the fault-tolerant constrained consensus problem for multiagent systems with communication delays. The graphs are first assumed to be directed and fixed.
