In order to quickly eliminate the swing angle of plate hoisting under wind load, an improved dynamic sliding mode control method is proposed in this paper. Firstly, the plate hoisting model under wind load is simplified into a double pendulum system, and the dynamic model of a double pendulum cable crane with wind disturbance is established. To enhance the coupling relationship between trolley displacement and double swing angle, a new coupling state vector for the double pendulum system is defined. On this basis, a dynamic sliding surface is constructed and then an integral function of the system's discontinuous term is established, essentially ensuring the continuity of the sliding surface and reducing the system's chattering characteristics. Finally, the stability of the system is rigorously proved by Lyapunov theorem and Barbalat lemma. The simulation and experimental results show that the controller proposed in this paper has a good effect on the anti-swing problem of plate hoisting under wind load.

The chemical process industry frequently encounters uncertainties, disturbances, and varying operational demands, necessitating robust control strategies to ensure safety, efficiency, and optimal performance. In addition, the non-linearities inherent in chemical processes complicate control efforts, as system behavior can vary significantly under different operating conditions. This paper presents the development and application of a Fuzzy Multi-model control (FMMC) system designed to manage chemical processes with long time delays at various operating points. The Takagi-Sugeno (T-S) fuzzy modeling approach, where each fuzzy rule represents a local linear system, is integrated with dynamic sliding mode control (DSMC) to enhance robustness and control performance under these varying conditions. To ensure the accuracy of the system's dynamics and provide a solid foundation for the proposed control strategy, the modeling was validated using the mean squared error (MSE). The parameters of the proposed controller were determined using Particle Swarm Optimization techniques (PSO), which optimize the effectiveness of the controller. The controller employs fuzzy switching, resulting in a streamlined DSMC formulation that effectively adapts to changes in the dynamic process. The results of the thermal processes performed in real-time experiments showed that the proposed controller not only maintained control within the operational range but also reduced the impact of disturbances and uncertainties. Moreover, its performance was validated using the indices IAE, ISE, and TVu, highlighting its suitability as an excellent solution for dynamic and uncertain conditions in the chemical process industry.

Despite the advantages of coupled-inductor single-input dual-output (CI-SIDO) DC-DC converter like small ripple, small size, and high efficiency, the coupling of inductor current leads to problems such as output cross-regulation. In order to reduce the cross-influence between the output branches for better dynamic performance of the system, this paper analyzes the reversibility of CI-SIDO Buck converters based on the inverse system theory, which constructs the inverse system in series with the original one to obtain two single-input single-output pseudo-linear subsystems to linearize and decouple the system. The adaptive dynamic sliding mode controller is also designed, and its performance is evaluated through simulations and experiments. The results demonstrate the superiority of the proposed control strategy to the traditional proportional-integral (PI) control method in terms of dynamic regulation performance and robustness.

Here, a novel control strategy based on sliding mode control for the single-stage boost inverter is presented. The goal is to achieve a system with robustness against inherent delays and variations in parameters, fast response, and high-quality AC voltage. Therefore, according to the idea of current-mode control, a new type of dynamic sliding mode control (DSMC) is proposed to improve the response performance on various input and parameter operation conditions. In comparison with the conventional controllers, the proposed DSMC utilized only a single loop while presenting attractive features such as robustness against parametric uncertainties and input delay by definition new sliding surfaces. Furthermore, the proposed system has a fast and chattering-free response, provides an appropriate steady-state error, good total harmonic distortion (THD), while its implementation is very simple. In a fair comparison with conventional sliding mode control, simulations and laboratory experiments verified satisfactory performance and effectiveness of the DSMC method.

This study aims to develop a feedback linearization adaptive dynamic sliding mode control strategy to solve the coupling problem between electrical and mechanical in a permanent magnet linear synchronous motor servo system (PMLSM) of CNC machine tools. To improve the dynamic and steady performance of the linear servo system, the feedback linearization control method is adopted in this paper. By coordinate transformation and state feedback, the affine nonlinear model of the motor is decoupled and linearized into an independent current subsystem and linear velocity subsystem. Based on the linearization model, a dynamic sliding mode controller is designed to reduce the dependence of feedback linearization control on the mathematical model of PMLSM and improve the robustness of the servo system. In addition, an adaptive control law is designed to estimate the uncertainty of the system and reduce the chattering. Simulation and experiment demonstrate that the proposed control strategy can not only effectively improve the performance of velocity tracking, but also enhance the robustness of the system.

tThis paper considers the design of internal model -based dynamic sliding mode control for a DC -DC boost converter. DC -DC boost converter transfer function model has non -minimum phase behavior with a zero in the right hand side of s -plane. The control structure considered in the paper constitutes an internal model which is so chosen that it compensate the non-minimum phase nature of the system due to a right-hand plane zero of s plane. Then, a dynamic sliding mode control (SMC) is designed to have a chattering free control signal. A PID type surface is chosen for the dynamic SMC and the surface parameters are tuned to have a critically damped tracking response. Simulation results are carried out for tacking and disturbance rejection and the results are compared with the basic internal model control (IMC) and two -degree -of-freedom IMC (TDF-IMC). It is observed that disturbance rejection for the dynamic SMC is much better than the basic IMC as well as TDF-IMC. Copyright (C) 2022 The Authors.

This study addresses the problem of mitigating vibration responses in tensegrity structures subjected to complex dynamic loading conditions. The overall purpose is to develop an effective control method to enhance the stability and performance of these structures. To achieve this, a fuzzy dynamic sliding mode control (FDSMC) method is proposed. The methodology involves deriving the state space expression of the controlled system based on the tensegrity structure's dynamic model, followed by designing a dynamic sliding mode controller using the reaching law. Fuzzy rules are incorporated to adaptively adjust the dynamic sliding mode parameters, accounting for uncertainties in controller parameters, thereby ensuring high efficiency and smooth controller output. A comparative analysis scheme, focusing on identical energy input on actuators, is utilized to evaluate the performance of various active vibration control methods. Two illustrative examples, a spatial double-layer tensegrity beam and a complex tensegrity spiral tower, are investigated in detail. The findings demonstrate that the FDSMC method significantly reduces structural dynamic responses and improves algorithm robustness compared to the conventional linear quadratic regulator (LQR) method, indicating its promising potential for relevant engineering applications.

Fuzzy disturbance observer-based dynamic sliding mode control for hypersonic morphing vehicles

This research discusses the attitude-tracking problem of hypersonic morphing vehicles (HMVs) in the presence of multi-source uncertainties. The hypersonic flight vehicle with variable-span wings is introduced. Considering the dramatic aerodynamic characteristic changes caused by morphing-span wings, strong robustness and great adaption are demanded. The sliding mode control technique is adopted to build the flight control system since the robustness is what the aircraft orders. In order to obtain fast attitude-tracking performance, the terminal function and adaptive laws are developed to achieve finite-time control with high adaptation to varying aerodynamic characteristics. For a hypersonic flight with guts, robustness enhancement is required. Therefore, a novel fixed-time disturbance observer is proposed to enhance the robustness against multi-source uncertainties. Unlike the existing finite-time observers, the settling time is independent of the initial conditions. Based on the disturbance observer and the adaptive technique, finite-time flight control is developed to provide strong robustness and adaptation, achieving uncertainty compensation. The effectiveness of the designed controller is revealed with the help of Lyapunov synthesis. Several flight scenarios are introduced to analyze the performance.(c) 2023 Elsevier Masson SAS.

The purpose of this paper is to develop a dynamic sliding mode controller (DSMC) based on the linoya and Altpeter approach and the sliding mode control (SMC) design procedure. The proposed approach is applied to chemical processes of high order with long dead time, and with inverse response. A simulation of a nonlinear mixing tank with variable delay, and an implementation on an Arduino Temperature control Lab are used to test the controller. A comparison of the proposed approach (DSMC), and the SMC based on Internal model control (IMC) is presented to evaluate advantages and disadvantages of the proposal. The results show that the approach of the DSMC presented in this work reduces the chattering, compensates the effect of external disturbances, and of the parametric uncertainties. To measure the controller's performance, the Integral Square Error index (ISE) and Total Variation index (TV) are used. (C) 2019 Elsevier Ltd. All rights reserved.
