Decoupled current control and sensor fault detection with second-order sliding mode for induction motor
TLDR
In this paper, the authors proposed a new decoupled control method for induction motor (IM) based on higher order sliding mode (HOSM) controller, which serves dual purpose by offering decouple control and sensor fault detection.Abstract:
This study proposes a new decoupled control method for induction motor (IM) based on higher order sliding mode (HOSM) controller. The proposed controller serves dual purpose by offering decoupled control and sensor fault detection. In this scheme, the decoupled control of d − q currents does not require the knowledge of the speed. The HOSM controllers play the same role as the compensation voltages produced by a decoupling compensator. From the compensation voltages, the speed can be estimated accurately through algebraic calculations. The estimated and actual speeds are then employed for fault detection algorithm to detect the fault. Simulations on a 1/4-hp three-phase IM in the presence of random measurement noise highlights the performance of the proposed approach for decoupling current control and robust sensor fault detection.read more

Strict Lyapunov Functions for the Super-Twisting Algorithm
Jaime A. Moreno,Marisol Osorio +1 more
TL;DR: The proposed Lyapunov functions ascertain finite time convergence, provide an estimate of the convergence time, and ensure the robustness of the finite-time or ultimate boundedness for a class of perturbations wider than the classical ones for this algorithm.

TL;DR: The introduction of a Lyapunov function allows not only to study more deeply the known properties of finite time convergence and robustness to strong perturbations, but also to improve the performance by adding linear correction terms to the algorithm.
