Summary: A novel quantization-based switched second-order sliding mode control design is proposed for nonlinear uncertain systems, which employs a new quantization strategy and state-space partition to attenuate the conservatism of control gain. All quantized regions are found to be globally invariant sets, leading to a monotonously consecutive decrease of control amplitude as the sliding variable converges to the origin through various uncertainty levels. The closed-loop system performance can be enhanced by adapting the quantization parameters, as evidenced by finite-time stability analysis and an assessment of the impact of quantization parameters on total convergence time. Simulation results demonstrate the efficacy and superiority of the proposed method compared to existing approaches.

Summary: A new class of regulators based on second-order sliding mode control is proposed in this paper. The synthesized control law provides a transient oscillatory process with decaying amplitudes, which converge to zero in finite time. The designed feedback provides an invariance property with respect to smooth external perturbation with less relay amplitude.

Summary: In this paper, a novel integrated guidance and control algorithm based on adaptive high-order sliding mode is proposed for reusable launch vehicle subject to unknown disturbances and actuator faults. We propose a time-varying barrier function-based adaptive control law to offset the effects of uncertainties. The remarkable feature of the developed algorithm is its ability to track the reference commands in finite time despite unknown disturbances and actuator faults, without designing the guidance law and attitude controller separately. Finally, the effectiveness of the proposed algorithm is confirmed by the simulation results.

Summary: A robust output feedback nonlinear control method is proposed for output tracking of an uncertain three-tank system using only the level sensor of the target tank. The system model is transformed into a canonical form with uncertainties through coordinate transformation. The state variables of the canonical system are estimated using a higher-order sliding mode differentiator based on the measurement of the target tank's liquid level. A continuous full-order sliding mode controller is then constructed based on the estimated state variables to eliminate the effects of both the additive and multiplicative uncertainties. Rigorous analysis is conducted to clarify the control performance, and the effectiveness of the proposed method is verified through experimental studies on the Inteco Multi-tank system.

Summary: This article proposes a novel event-triggered second-order sliding mode (SOSM) control method for uncertain nonlinear systems. A new switched triggering mechanism is constructed using three predesigned saturated-like functions. An event-triggered SOSM controller is designed under the proposed triggering mechanism to ensure finite-time convergence of the SOSM system states to a domain of the origin, which prevents escape from the domain. To avoid Zeno behavior, two positive minimum inter-execution intervals are obtained based on different triggering conditions. The effectiveness of the control strategy is verified through a simulation study.

Summary: This article introduces a method for representing the attitude of a rigid body, which uses rotation matrices defined on the special orthogonal matrix group SO(3) to provide unique, global, and nonsingular solutions. For attitude control systems operating on the Lie group SO(3) x R3, a second-order sliding surface is constructed and proven to be a Lie subgroup, ensuring almost global asymptotic stability of the reduced-order dynamics at the equilibrium state. A fault-tolerant controller is then designed based on this new sliding-mode surface to handle actuator faults and external disturbances in attitude control systems. Numerical simulations and implementation in a semi-physical simulation system of an air-bearing platform demonstrate the effectiveness of this new method in practical spacecraft engineering.

Summary: This study discusses the research and development, design ideas, and control systems of MEMS gyroscopes, and introduces a method to improve the efficiency of gyroscopes by matching the resonance frequencies of resonators. Due to the presence of noise, navigation system design faces difficulties, while the proposed method can determine the error in the output. In order to minimize the chattering effect, second-order sliding mode control is used.

Summary: We propose a solution to the problem of formation consensus control for second-order nonholonomic systems using output feedback. Our contribution is a distributed consensus controller for force-controlled nonholonomic systems when the forward and angular velocities are not measurable. The main result establishes the uniform global asymptotic stability of the closed-loop system, ensuring robustness against bounded disturbances.

A multi-agent approach is used to address the problem, with robustness achieved through the use of an integral sliding mode control term. Global voltage restoration stability is demonstrated through a Lyapunov-Krasovskii analysis, despite the presence of communication delays.

Summary: This article introduces a novel local interaction rule that enables leader-following and leader-less consensus in a network of nonlinear uncertain first-order agents communicating through a connected and switching graph topology. The proposed rule ensures consensus is achieved after a finite settling time, with an upper bound independent of the initial conditions of the agents' states. This fixed-time convergence property is achieved through homogeneous polynomial terms in the interaction rule, supported by a Lyapunov-based analysis and simulation results.

Summary: This study investigates a network of agents modeled by wave PDEs, with one leader agent and multiple follower agents who asymptotically track the leader's state. A linear interaction protocol controlled by Neumann-type actuation and analyzed using a Lyapunov-based approach is proposed, ensuring exponential synchronization through simple tuning rules. Additionally, an exponential ISS relation characterizing the impact of boundary and in-domain disturbances on tracking accuracy is derived for the closed loop system.
