In this paper, we propose a new design for a multivariable super-twisting algorithm, which does not require the exact knowledge of the system input matrix. In addition, by means of a nonlinear (state-dependent) time scaling we propose a new algorithm with variable gains which is able to present global stability properties for wider class of nonlinear disturbances. The latter can be analysed using the same theoretical framework as in the case of constant gains. The theoretical results are illustrated by simulations.

Control of complex dynamical systems such as electrohydraulic systems is challenging. This paper presents force control of an electrohydraulic actuator using the super-twisting algorithm (STA). The STA is one of the most promising high-order sliding-mode control algorithms. It guarantees robustness with respect to modeling errors, uncertainties and external disturbances while reducing the chattering phenomenon found in the conventional sliding-mode control (SMC) algorithm. In this paper, the STA was utilized to achieve a robust nonlinear controller for force control of an electrohydraulic actuator. The benefits offered by the STA-based control compared to the conventional SMC-based control were demonstrated through numerical simulations. Finally, experiments on a real-life electrohydraulic system were conducted to illustrate the success and effectiveness of the STA-based controller.

This paper proposes analysis of boost converter with super-twisting algorithm under sliding mode operation in continuous conduction mode. The super-twisting algorithm reduces the chattering effect which is inherent in conventional sliding mode control. This control minimizes the initial current peak and provides output voltage regulation irrespective of input voltage perturbation and load changes. The converter is also controlled by a PI controller and the performances under each controller are compared.

This paper develops a super-twisting., algorithm controller via a nonlinear disturbance observer for a DC motor system subject to matched and unmatched uncertainties. The proposed controller is based upon a novel Nonlinear Disturbance Observer structure which uses the concept of total disturbance estimation in order to estimate simultaneously the matched and the unmatched uncertainties in the system. This estimation is incorporated then in a composite observer based controller where the stability analysis is given. Simulations results illustrate the effectiveness of the proposed controller compared to other some existing control designs and show its advantages in terms of disturbance rejection, nominal performance recovery and chattering reduction.

A super-twisting-Like algorithm and Its Application to Train Operation Control With Optimal Utilization of Adhesion Force

The friction between wheel and track is usually called adhesion force, and it is the critical factor for the movement of trains. On one hand, excessive driving force of a train may lead to insufficient utilization of the adhesion effect and cause wasted energy;on the other hand, insufficient driving force of a train brings inefficient train operation. To balance the issues of energy consumption, operational efficiency, and security, it is necessary to control a train to obtain its maximal adhesion force, particularly in the cases of fast acceleration and emergency braking. However, since engineering experiments indicate a complex nonlinear relationship between the adhesion force and the slip ratio of a train, such a control problem is difficult and challenging, particularly when the optimal slip ratio is unknown. Facing this problem, this paper proposes a novel control method based on the modification of the famous super-twisting sliding mode algorithm, and rigorous mathematical analysis is given to guarantee the ultimate boundedness of the proposed algorithm. Furthermore, by considering four different control scenarios, detailed control and estimation algorithms are both proposed. Simulation result verifies that the proposed control strategy can control the train to obtain its maximum adhesion force.

Robust Tracking Control of Piezoelectric Actuators Using super-twisting Sliding Mode With Bouc-Wen Hysteresis Model-Based Enhanced Jaya algorithm

引用

IEEE ACCESS 2025年 13卷 15547-15555页

This paper introduces a super-twisting Sliding Mode Control (STSMC) strategy integrated with a Bouc-Wen hysteresis model for tracking control of the piezoelectric (PZT) actuator. The Bouc-Wen model, which captures the nonlinear hysteretic behavior of the PZT actuator, is estimated using a modified Jaya algorithm enhanced with L & eacute;vy flight distribution (called LeJaya). This modification improves the update mechanism by using L & eacute;vy flight distribution for better global search capabilities and employing an adaptive population scheme to optimize both exploration and exploitation. The STSMC with Bouc-Wen hysteresis is designed to overcome the chattering phenomenon and guarantee global asymptotic stability. The stability control of the PZT system is verified by Lyapunov's Law. Simulation results demonstrate the robustness and effectiveness of the proposed method in comparison to classical sliding mode control (SMC), neural sliding mode control (RBFSMC), and fuzzy sliding mode control (FuzzySMC), highlighting improved tracking performance and removed chattering phenomena. The proposed method offers a promising solution for precise and stable control of the PZT actuator in the presence of hysteresis.

This study proposes an intelligent robust controller to improve the performance of the multifunctional grid connected photovoltaic (PV) system using the phase-locked loop (PLL). The novelty of this research is the use of a new strategy, called super-twisting algorithm (STA) based on genetic algorithm (GA) to improve the performance of the direct power control (DPC) with PLL technique and maximum power point tracking (MPPT), where DPC-STA-GA is used to control the active power filter. This proposed nonlinear technique is used to increase the power quality of the PV system under different conditions (variation of the nonlinear load, random nature of the irradiance solar and temperature,...etc). On the other hand, the STA-GA controller is successfully applied to control the DC link voltage of the multi-functional voltage source inverter. Durability and ease of implementation are among the most prominent features of the DPC-STA-GA with PLL technique to reduce the reactive and active power ripples compared to the DPC technique. The suggested intelligent nonlinear control ensures the harmonic current compensation and the transmission of PV energy to the electric grid and or the nonlinear load with high quality. To implement and verify the proposed controls with the PLL technique, Matlab software is used for this purpose, with the study of the behavior of the proposed controls based on STA-GA controllers with the PLL compared with the DPC in different conditions. The simulation results demonstrated the contribution of the DPC-STA-GA with the PLL in improving the performance, efficiency, effectiveness, and durability of the system under normal and abnormal conditions, where the proposed control reduced overshoot value in DC bus voltage by 100% compared to proportional-integral controller. In addition to reducing the value of THD of current compared to DPC and DPC-STA by 18.82% and 43.33%, respectively, in the case of solar radiation equal 1000 W/m2.

Novel control strategy for robustness of two DOF Smith predictor via active disturbance rejection method

JOURNAL OF THE FRANKLIN INSTITUTE 2025年第2期362卷

This paper presents a novel control strategy that employs a Smith predictor for large delay- time systems. Although the classic Smith predictor structure is superior for large delay-time compensation, it exhibits weaknesses when confronted with time varying disturbances, parameter uncertainties, and unmodeled dynamics. To overcome this intrinsic problem of the Smith predictor, this paper proposes a novel two degrees-of-freedom Smith predictor structure with two decoupled controllers. For fast reference tracking and robustness against disturbance, the reference controller is designed as a sliding mode controller and is developed using linear quadratic regulation and a modified smooth super-twisting algorithm. The perturbation rejection capability is enhanced by using an adaptive method and sliding mode based active disturbance rejection control. Thus, the developed control system can achieve robustness, accurate trajectory tracking, and fast response despite disturbances, noises, and mismatched errors. The simulation results demonstrate the effectiveness of the proposed control strategy in reducing the delay-time and system uncertainties, resulting in improved PMSM speed control.
