This paper further investigates the problem of reachable set estimation (RSE) for a class continuous-time singular systems with time-varying delay. First, we use relaxed Lyapunov–Krasovskii functional to tackle RSE problem. does not need all matrices concerned be positive definite. In addition, novel weighted integral inequality and time-delay partition approach are utilized reduce conservatism in results. Based on these methods, sufficient conditions form linear matrix inequalities established. Finally, correctness validity results demonstrated by three simulation examples.

Abstract This study presents a novel event-triggered finite-time stochastic control method for robot manipulator. The random moment of inertia the manipulator system is expressed by building dynamic model, and parameter variation disturbance estimated using configuration neural network. An controller with uncertain rejection proposed, which not only realizes stability tracking error system, but also guarantees safety motion velocity, robustly improves accuracy Compared existing works, obvious feature proposed that it can simultaneously solve save communication resources, ensure reach steady state in finite time. We discuss effectiveness method. Simulation comparative analysis results further show be updated less frequently while guaranteeing robust performance

Abstract This paper proposes an adaptive control scheme with finite‐time convergent property based on integral sliding mode to achieve trajectory tracking of rigid robotic manipulators. The novel gain can be adjusted automatically the system disturbance, as long disturbance and its derivative are bounded without requiring more information. Therefore, chattering effect mitigated obviously. global robustness is guaranteed by Lyapunov stability analysis. Finally, simulation a two‐link manipulator given show that desired performance obtained proposed approach.
