Summary: This article investigates the problem of finite-time adaptive fuzzy tracking control for multi-input and multi-output (MIMO) nonlinear systems with input saturation. A new finite-time command filter and modified error compensation mechanism are introduced to address complexity explosion and filter error effects. The proposed finite-time adaptive control scheme guarantees finite-time bounded signals and regulation of output tracking errors to a small neighborhood of the origin. Numerical comparison example verifies the effectiveness of the proposed control scheme.

Summary: This article discusses the problem of finite-time adaptive fuzzy prescribed performance control via output-feedback for nonstrict-feedback nonlinear systems. By designing a fuzzy state observer and a novel finite-time command filter, the authors propose a control strategy that can converge the output tracking error to a residual set within prescribed performance bound in finite time.

Summary: This article proposes a solution to the cooperative fault-tolerant control problem for networks of stochastic nonlinear systems with actuator faults and input saturation. Fuzzy neural networks are used to estimate unknown functions and stochastic disturbance terms, while a smooth nonlinear function is constructed to estimate the saturation function. A novel adaptive fault-tolerant control protocol is proposed using backstepping design technique, and the stochastic Lyapunov functional strategy is used to prove convergence and boundedness of the closed-loop systems.

Summary: This article investigates the problem of adaptive fuzzy optimal distributed consensus control for stochastic multiagent systems (MASs) with full-state constraints and nonaffine nonlinear faults. Fuzzy logic systems are employed to identify the unknown nonlinearities. To solve the problem of optimal state constraint control, a barrier Lyapunov function based optimal cost function is designed. By introducing Butterworth low-pass filter into control design, the deleterious effects raised by nonlinear fault can be compensated. By utilizing adaptive dynamic programming algorithm in critic-actor construction, a fuzzy adaptive distributed optimal consensus fault-tolerant control method is proposed, which can ensure that all signals of the controlled system are semiglobally uniformly ultimately bounded in probability, and outputs of the follower agents keep consensus with the output of leader. In addition, system states are all not exceeded their constrained bound. Finally, simulation results are provided to illustrate the feasibility of the developed control method and theorem.

Summary: This article investigates the distributed containment control problem for high-order stochastic nonstrict-feedback nonlinear multi-agent systems. An auxiliary virtual controller is designed to overcome the difficulty of unknown control input gain, and the unknown terms are estimated by introducing radial basis function neural networks.

Summary: An adaptive neural control strategy is proposed for uncertain 2DOF helicopter systems with input saturation and time-varying output constraints. A radial basis function neural network is utilized to estimate the uncertainty terms in the system, while an adaptive auxiliary parameter is introduced to compensate for the composite disturbance caused by saturation error and external disturbance. An asymmetric barrier Lyapunov function is employed to address the constraint violation of system output. The closed-loop stability of the system is verified through Lyapunov theory analysis, and simulation results demonstrate the effectiveness of the proposed control strategy.

Summary: This article studies the adaptive optimized formation control problem for second-order stochastic multiagent systems with unknown nonlinear dynamics. Fuzzy logic systems are used to approximate the nonlinear functions in the control design. By employing the actor-critic architecture and Lyapunov stability theory, the proposed optimal formation control strategy ensures that all the error signals are bounded in probability. Simulation examples verify the effectiveness of the proposed formation control approach.

Summary: This paper considers finite-time leader-following consensus control for high-order stochastic nonlinear multi-agent systems with input constraints. It designs a finite-time consensus tracking controller based on adaptive fuzzy command filtered backstepping, uses a fractional power form-based error compensation method, and employs a fuzzy logic system to approximate unknown nonlinear functions. The practical finite-time stability in mean square is assured under the given control method, and simulation results show the proposed controller's effectiveness and feasibility.
