“…The ISMC is a new version of the SMC, which has a robust control characteristics, and it can eliminate the reaching phase by enforcing the system states to be on the sliding manifold right from the beginning [23,25]. Unlike other control approaches, the ISMC does not have a reaching phase, and the order of motion remains unchanged during the sliding mode [27,28].…”

“…The existing literature offers three distinct categories of control strategies for VSbW systems: classical control techniques (e.g., PI, PD, and PID), intelligent control strategies, and robust control strategies. The sliding mode control (SMC) is a notable robust control methodology that ensures system invariance to perturbations during sliding motion [23,24]. The SMC consists of two phases: the reaching and sliding phases [25].…”

In this research paper, a recent robust control scheme was proposed and designed for a VSbW (vehicle steer-by-wire) system. Using an integral sliding mode control (ISMC) design based on barrier function (ISMCbf) could improve the robustness of ISMCs. This control scheme, due to the characteristics of the barrier function, can improve the robustness of the proposed controller better than that based on the conventional SMC or integral SMC (ISMC). The ISMCbf scheme exhibits all the benefits of the conventional ISMC with the addition of two main advantages: it does not require prior knowledge of perturbation bounds or their derivatives, and it can effectively eliminate the chattering phenomenon associated with the classical ISMC due to the smooth characteristics of the barrier function. On the other hand, in terms of the design implementation, the ISMCbf is simpler than the ISMC. In this study, the mathematical dynamical model of the VSbW plant was first presented. Then, the control design of the ISMCbf scheme was developed. The numerical results showed that the proposed scheme is superior to the conventional ISMC. The superiority of the proposed ISMCbf controller versus the classical ISM has been evaluated under three different uncertain conditions, and three scenarios can be deduced: a slalom path, quick steering, and shock disturbance rejection. Furthermore, a comparative analysis with other controllers from the literature has further been established to show the effectiveness of the proposed ISMCbf.

“…In sliding mode control, the control law consists of two parts: equivalent part and switching part. The equivalent part of control signal is responsible for bringing the trajectory from initial states to the sliding surface, while the switching part tries to keep the trajectory on the sliding surface until reaches the origin [11,12]. The sliding surface is given by…”

This study presents a performance comparison between a synergetic controller (SC) and a sliding mode controller (SMC) applied to a pendulum system. Initially, the mathematical model of the pendulum system is established. Subsequently, the design of both synergetic and sliding mode controls is elaborated, leading to the development of control laws for the proposed controllers. The effectiveness of the pendulum system controlled by SC and SMC has been validated through numerical simulations. These simulations revealed that the control signal exhibits chattering behaviour in the case of SMC, while this phenomenon is absent with the SC, demonstrating a distinct difference in performance between the two control systems.

“…Moreover, these robust controllers have discontinuous term that causes chattering phenomenon which means these controllers need some kind of approximation to attenuate it. From the previous drawbacks, the motivated that lead to overcomes this problem by Husain and Ridha [14] to design Integral Sliding Mode Based on barrier function (ISMCbf). They compared three types of controllers: SMC, Integral Sliding Mode Controller (ISMC) and ISMCbf to control the behavior of ATMD placed on the top floor of a scaled structure.…”

Seismic effects control in recent years has attracted considerable attention to reduce their effects for the safety of humans and structures. Therefore, in this work Integral Sliding Mode Control Based on Barrier Function (ISMCbf) is applied for the first time to regulate the displacement of a three-story scaled structure against earthquake excitation. This new type of controller does not need any information of the upper bound of the disturbance. Firstly, the controller is applied to a semi active Magneto Rheological Damper (MRD) and compared to the performance of Active Tuned Mass Damper (ATMD) under the effect of two different simulated earthquakes: time scaled El Centro 1940 earthquake and Mexico City earthquake. ISMCbf with MRD reduced the displacement of the structure with lower required controlled force as compared to ATMD with ISMCbf behavior. Secondly, the efficiency of ISMCbf with MRD is shown when compared to other controllers with MRD from previous studies.
