“…These performances are obtained with the help of the new supervisor that was able to drive the control during all operation zones, by generating a stable decision that can ensure good switching from one regulator to another. Note that this supervisor requires less computing time compared to that used in [13][14]18]. It can detect the presence of external disturbances and activates the SMC to interfere with variable percentages linked to the speed drops.…”

“…On the other hand, the control improvement applied in this work can be more illustrated by comparing the present hybrid controller with other techniques based on the same principle. The authors of [13] integrated the fuzzy logic into the basic sliding mode structure in order to minimize chattering. This regulator was used in transient regimes, while a nonlinear controller was adopted for the steady state through a two-dimensional supervisor requiring a derivative to determine the correct supervisor decision.…”

Induction Motors are the most used machines in the industrial field since the last century, due to their low cost, high robustness with satisfactory performance. However, they are still difficult to control compared to the DC motor because of the non-linearity presented in the mathematical model. Sliding mode theory is often used to develop powerful control against various internal and external disturbances. However, the chattering problem caused by the attractive part of the regulator is a serious problem for its applications. In this paper, the proposed solution for having an optimal performance consists in combining the Sliding Mode Control with an anti-windup proportional-integral regulator. This is achieved through a simple linear supervisor that can activate the sliding mode at start-up and transient regimes while making the second controller drive the steady state. The asymptotic stability of the delivered control signal is ensured via the Lyapunov method. This allows us to benefit from the advantages of the two regulators without having their disadvantages. This new hybrid technique can potentially offer very promising results in terms of robustness and control efficiency. The validation of this theory was carried out by simulation and then by practical implementation using a dSPACE-DS-1104 control board. The obtained results show a high-performance control with very good robustness against parametric variations and remarkable stability during all different operating zones.

“…In Rkhissi et al (2017), a new IM control law is developed using the Backstepping design associated with the robust integral sign of the error (RISE) technique, which is used to compensate the load torque disturbance under specific conditions. We can find in literature other approaches that combine Backstepping with other nonlinear techniques such as fuzzy logic and sliding mode control (Aichi et al, 2018a). These methods can ensure high-performance dynamic and remarkable robustness to the various disturbances; because it can exploit the benefits of each theory without having these inconvenient, but the complexity of the algorithm will be increased.…”

This work proposes a robust control scheme of a three-phase induction motor using a new Backstepping approach based on variable gains. Because of the saturation blocks that are essential to protect the control system, the use of conventional integral Backstepping could lead to a modest performance represented by overshooting and strong vibrations in transitional regimes that cause overcurrent. To develop an efficient and simple control algorithm, the variable gains propriety is used in the speed controller to offer a quick response without overshooting with good robustness against external disturbances. The same property has been introduced in current regulation by a different mean in order to develop a new solution to solve obstacles related to very low-speed operations. The asymptotic stability of the global control is proven by Lyapunov theory. The improvement of the new version compared with the classical one was verified by a brief comparative study based on simulation results. The proposed algorithm has been implemented in a dSPACE DS 1104 card, to analyze the real-time motor performance, and to test control sensitivity against parametric variations. The obtained results show a remarkable improvement of the new control concerning rapidity and stability of transient regimes, overtaking elimination and reduction of starting current, with a low algorithm sensitivity against parametric variations. We have also been able to confirm that the new current control method can guarantee optimal regulation in order to achieve a high-performance operation at very low-speed zones, in the presence of various internal and external disturbances.

In this study, a filter‐based control scheme is proposed for dc–dc buck‐type converters. Primarily, this control scheme reduces costs by requiring only a single output voltage measurement, removing the need for potentially noisy current measurements. The proposed controller is compared with a Type III error amplifier, which is a linear controller commonly used for buck‐type converters. The performance of these controllers is compared when applied to linear and non‐linear loads. A Lyapunov stability analysis is utilised to demonstrate the system stability of the proposed control scheme. Experimental results demonstrate excellent voltage regulation and insensitivity to the load variations for the proposed controller as compared to Type III controller.
