In the continuation of authors' studies on control and estimation methods for Single-Phase Induction Motor (SPIM), a new observer-based controller using High Order Sliding Mode (HOSM) algorithms is proposed here. This observer-controller scheme only uses measurements of the rotor speed and stator currents. The complete scheme is robust to uncertainties in(More)
A Sliding Mode (SM) Block Control is proposed to control an Antilock Brake System (ABS). The control problem is to achieve reference tracking for the slip rate, such that, the friction between tyre and road surface is good enough to control the car. The closed-loop system is robust in presence of matched and unmatched perturbations. To show the performance(More)
A Leak Detection and Isolation (LDI) algorithm with a State Observer is designed and tested in simulation to locate a water-leak on a pipeline. Most of the works presented in the literature make some linearization in the model limiting the performance of the approach. In order to avoid this situation, in this work, the State Estimation is designed with the(More)
— This paper deals with the control of an Anti-lock Brake System (ABS) assisted with an active suspension. The main objective is to track the slip rate of a car and ensure a shorter distance in the braking process. For the ABS subsystem an integral nested sliding mode controller based on the block control principle is designed. On the other hand, for the(More)
In this paper, a new class of recurrent neural networks which solve linear and quadratic programs are presented. Their design is considered as a sliding mode control problem, where the network structure is based on the Karush-Kuhn-Tucker (KKT) optimality conditions with the KKT multipliers considered as control inputs to be implemented with fixed time(More)
This paper focus on an approach based on sliding mode observers to estimate the position and pressure of a leak in a water plastic pipeline. Two observers are designed, the first one is based on First Order Sliding Mode (FOSM) and the second one is based on Super-Twisting algorithm. Convergence proofs are presented. The two derived observers are implemented(More)
The purpose of this paper is to compare two different algorithms used to detect and isolate water leaks in a pipeline. One method is based on a Sliding Mode Observer and the second method is an Algebraic method obtained from the pipeline model in steady state. Because of the simplicity of both methods, they can be easily implemented. The methods were tested(More)
The aim of this paper is to introduce a new recurrent neural network to solve linear programming. The main characteristic of the proposed scheme is its design based on the predefined-time stability. The predefined-time stability is a stronger form of finite-time stability which allows the a priori definition of a convergence time that does not depend on the(More)
—A new sliding mode observer-based controller for single-phase induction motor is designed. The proposed control scheme is formulated using block control feedback linearization technique and high order sliding mode algorithms with measurements of the rotor speed and stator currents. The stability of the complete closed-loop system included the rotor flux(More)
