(2019b) constructed a neural network–based controller for a class of strict-feedback nonlinear systems with state constraints and input delay. Log-type BLF and log-type integral barrier Lyapunov function (IBLF) are combined with adaptive control to deal with state constraints ( Cui et al., 2020 Liu et al., 2018, 2021b Wang et al., 2021a). Simulation results are provided to demonstrate the effectiveness of the proposed control scheme.īarrier Lyapunov function (BLF Tee et al., 2009), extremum-seeking control ( DeHaan and Guay, 2005), and model predictive control ( Mayne et al., 2000) are the methods that deal with nonlinear systems with state constraints.
The closed-loop signals are proved to be practical bounded. A novel finite-time delay compensation mechanism is proposed to remove the impact of input delay. The time-varying asymmetric barrier Lyapunov function (TVABLF) and command-filtered backstepping design are applied to alleviate the significant challenges caused by the backstepping approach and full-state constraints. A first-order Levant differentiator is employed to replace the command filter for estimating the virtual control signals in finite time. A command-filtered backstepping design is used to decrease computational burden.
The existing control method either ignores the effect of input delay or converges asymptotically in infinite time. This paper examines a finite-time command-filtered backstepping control proposed for a class of strict-feedback nonlinear systems with input delay and time-varying asymmetric full-state constraints.
