With the price decreasing of the pneumatic proportional valve and the high performance micro controller, the simple structure and high tracking performance pneumatic servo system demonstrates more application potential in many fields. However, most existing control methods with high tracking performance need to know the model information and to use pressure sensor. This limits the application of the pneumatic servo system. An adaptive backstepping slide mode control method is proposed for pneumatic position servo system. The proposed method designs adaptive slide mode controller using backstepping design technique. The controller parameter adaptive law is derived from Lyapunov analysis to guarantee the stability of the system. A theorem is testified to show that the state of closed-loop system is uniformly bounded, and the closed-loop system is stable. The advantages of the proposed method include that system dynamic model parameters are not required for the controller design, uncertain parameters bounds are not need, and the bulk and expensive pressure sensor is not needed as well. Experimental performance, as compared with some existing methods. results show that the designed controller can achieve better tracking

IEEE TRANSACTIONS ON CYBERNETICS 2025年第1期55卷 259-268页

The primary focus of this article centers around the application of sliding mode control (SMC) to semi-Markov jumping systems, incorporating a dynamic event-triggered protocol (ETP) and singular perturbation. The underlying semi-Markov singularly perturbed systems (SMSPSs) exhibit mode switching behavior governed by a semi-Markov process, wherein the variation of this process is regulated by a deterministic switching signal. To simultaneously reduce the triggering rate and uphold the system performance, a novel parameter-based dynamic ETP is established. This protocol incorporates weight estimation of a radial basis function neural network (RBFNN) and introduces two internal dynamic variables. Following the Lyapunov's theory, sufficient criteria are established for ensuring the mean-square exponential stability of the resulting system. Additionally, an SMC scheme based on the convergence factor is designed to fulfill reachability conditions. Finally, two examples are carried out to validate the solvability and applicability of the attained control methodology.

Aiming at the shortcomings of the damping performance of the traditional tuned liquid damper (TLD), a damping technology scheme that organically combines the TLD with the active control device is proposed to form an active tuned liquid damper (ATLD) based on the sliding mode control algorithm. Based on the intensive analysis of ATLD damping characteristics, the ATLDsingle degree of freedom structural mechanics model is established according to the composite damping of the structure by the active control force and the passive control force of TLD. To verify the accuracy of the theoretical mechanical model of ATLD and to investigate the effects of structural period and seismic site category on the real damping performance of ATLD, three different period single-degree-of-freedom steel framework test models are adopted to complete the seismic simulation shaking table tests. The sliding-mode control algorithm with a steep saturation function is proposed to eliminate the structural jitter effect. The dynamic test and theoretical results show that the numerical calculation results and the test results have good agreement in terms of the peak displacement and the root mean square. The introduction of an active control device into TLD can significantly improve the seismic performance of traditional TLD. ATLD can produce an excellent seismic control effect on the controlled structure under all kinds of site conditions, and the damping effect is better with the increase of the site category. ATLD is more suitable for medium and high-rise buildings, and it has a good prospect for engineering applications.

Hybrid controller configuration for master-slave paralleling of DC-DC converters with improved sliding manifold

This paper focuses on sliding mode controller (SMC)-based master-slave parallel operation of DC-DC converters using a modified sliding manifold to achieve a fast dynamic response and very low steady-state error. The converter performance is analyzed in a novel way starting from a simple case of paralleling of two converters and then concept is extended for parallel operation of multiple converters. An investigation of the choice of the sliding surface on the performance of parallel converter is carried out in detail, and a mathematical design guideline for sliding coefficients for the proposed manifold for the master converter is derived to achieve stable operation. The proposed manifold ensures an improved dynamic response with an excellent steady-state accuracy in stand-alone mode. However, when it is incorporated with master-slave control for parallel operation with finite tie wire impedance, there is a degradation in the steady-state accuracy. In order to improve the steady-state performance of the sliding mode controller, two new hybrid (SMC + PI) controllers are proposed and implemented for parallel connected DC-DC converters. Finally, the proposed SMC techniques are verified through simulation study and through a scaled down experimental (laboratory) prototype.

This research paper investigates a protocol -based sliding mode control (SMC) approach for singularly perturbed systems with switching parameters and random occurring deception attacks. The mode switching behavior of the original system is regulated using a semi-Markov process, and a novel and more efficient mode monitoring method is proposed, distinct from the conventional hidden Markov model. Furthermore, to reduce the triggering rate while maintaining control performance, a probability -based event triggering protocol is introduced. By employing the proposed scheme along with Lyapunov theory, sufficient criteria for parameter correlation are established to ensure asymptotic stability. The designed sliding mode control incorporates a convergence factor to enhance the control performance. Finally, the feasibility and practicality of the proposed control strategy are verified through simulations using two practical models.

In this paper, the fixed -time control for a class of second -order nonlinear system is investigated. Considering that the presented fixed -time controllers in most existing results are singular, we aim to develop a fixed -time sliding mode controller without singularity. The contribution of this work is not only developing a novel cosine function -based sliding function to ensure the fixed -time convergence of system states on the sliding surface but also designing a novel sliding mode controller to guarantee the fixed -time stability of the obtained closed -loop system without singularity. First, it is proven that the system trajectories converge to the origin in a fixed time on the novel proposed cosine function -based sliding surface. It is further proven by Lyapunov theory that the obtained closed -loop system under the presented controller is fixed -time stable. Moreover, the chattering problem is settled by slightly modifying the presented controller. It is also proven that the system trajectories converge into a small neighborhood of the origin in a fixed time. The results are illustrated in the simulation.

This paper focuses on the finite-time sliding mode control for singularly perturbed switching systems in the presence of sojourn probabilities. To effectively capture the dynamic behavior of singularly perturbed switching systems, a generalized framework of piecewise-homogeneous sojourn probabilities is established. Additionally, a novel event-triggered protocol is introduced to alleviate transmission frequency, making use of dynamic quantization and adjustable triggering thresholds to accommodate system state fluctuations. Besides, an asynchronous sliding mode control law is designed, using a suitable sliding function and hidden-Markov model strategy, to ensure the trajectory of the resulting singularly perturbed switching systems reaches the predefined sliding surface within a finite-time interval. Finally, the proposed method is validated using a numerical example and two practical models, demonstrating its effectiveness and practicality. \(c) 2023 Elsevier Ltd. All rights reserved.

This paper proposes a new car-following model to describe the characteristics of the urban Internet of vehicle (IoV) of the "End-Edge-Cloud"architecture. The stability of the proposed CF model is analyzed using the perturbation method. Furtherly, in order to overcome the disturbances in the operation of the newly proposed system in this paper, a sliding mode controller is designed based on non-homogeneous terminal sliding mode variables, and after setting up the controller, the dynamic performance of the system is analyzed by solving the linear inhomogeneous differential equation and the Lyapunov method, and it is proved that the system can converge in finite time. Finally, the rationality of the model proposed in this paper and the significant improvement in the dynamic performance of the system under the action of the controller are effectively demonstrated through numerical experiments conducted in MATLAB and simulation experiment carried out in the ROS-Gazebo environment.& COPY;2023 Elsevier B.V.
