“…Compared to other control methods, SMC has attracted significant interest due to its simplicity, low sensitivity to system parameter variations and high robustness to external disturbances [2]. Therefore, SMC has been developed and applied widely in many applications, including robot manipulators [3], cable-driven manipulators [4], [5], power systems [6], multiagent systems [7] and guidance law design [8].…”

This paper proposes a nonsingular terminal sliding mode control scheme with fast fixed-time convergence for a class of second-order nonlinear systems in the presence of matched uncertainties and perturbations. First, based on fixed-time stability theory, a novel stable system is proposed. Then, using the fixed-time stable system, a fast fixed-time nonsingular terminal sliding surface is derived. The settling time is independent of the initial system state and can be set in advance with the design parameters; the upper-bound of convergence time is derived from the Lyapunov theory. Moreover, the proposed control scheme has an advantage in convergence rate over existing results and achieves better control performance with low control energy cost. The simulation results for a tracking system with a single inverted pendulum are presented to validate the effectiveness and superiority of the proposed control method.

This paper investigates the bipartite consensus problem of heterogeneous multiagent systems with diverse input delays. Based on the systems composed of first-order and second-order agents, the novel control protocols are designed. Using frequency-domain analysis and matrix theory, the corresponding upper bounds of the allowable delays are obtained under the undirected topology and directed topology, respectively. Finally, simulation examples are given to verify the theoretical analysis.

“…I N this era of rapid development of science and technology, people need to keep improving the performance of actual industrial systems. Any actual physical system is more or less nonlinear, such as hydraulic servo system [1], robot control system [2], multi-agent [3], spacecraft system [4] and so on. Control methods for nonlinear systems have sprung up rapidly, such as backstepping control [5], [6], sliding mode control (SMC) [4], [7], [8], adaptive control [9], etc.…”

This paper proposes a novel predefined time nonsingular terminal sliding mode control (TSMC) based on radial basis function neural network (RBFNN) for nonlinear systems. Firstly, a new lemma of tunable predefined time stability (PTS) is proposed, where the introduction of an adjustable parameter can adjust the stability time of the system and makes the design of the controller more flexible. Secondly, based on the proposed lemma, a new control method is proposed, which not only guarantees the PTS of the system, but also solves the singularity problem of the traditional TSMC and the problem of unknown model information. Finally, through comparative simulation, it is verified that the proposed method has good control performance.
