Observer-Based Adaptive Prescribed- Time H ∞ Coordinated Control for Multiple Robot Manipulators With Prescribed Performance and Input Quantization

“…The composite H ∞ controller (26) proposed in this paper is guaranteed to be globally prescribed-time convergent when the gain L 2 satisfies the condition that does not exceed γ , and the prescribed-time controller in (27) should be highly robust. The multi-RM systems are not only prescribed time stable, but also have good immunity to interference.…”

“…(4) Aiming at the problem of aggregate disturbances such as model nonlinear terms and unknown time-varying disturbances, unlike the approximation estimation using radial basis neural networks [26] and fuzzy neural networks [27] in previous studies, a prescribed-time H ∞ formation control strategy is proposed in this paper, which ensures that the initial conditions set by the system are not affecting the convergence speed within the prescribed time. In addition, the system has fast response performance and good robustness when the gain L 2 is also not greater than the given γ .…”
