Whale Optimization Algorithm Enhances the Performance of Knee-Exoskeleton System Controlled by SMC

Zahraa Ali Waheed; Amjad Jaleel Humaidi

Volume 23, Issue 2 , June 2023, , Page 125-135

https://doi.org/https://doi.org/10.33103/uot.ijccce.23.2.10

Abstract
  Physiotherapeutic exoskeleton devices have recently been developed to helppeople rehabilitate impaired limb mobility and replace the use of physiotherapists. Suchsystems are characterized by high nonlinear and time-varying coefficients. In order tocope with such difficult control challenges, a need arose ...  Read More ...

Robust Controller Design for Flexible Joint Based on Back-Stepping Approach

Ahmed Mohsen Mohammad; Shibly Ahmed AL-Samarraie

Volume 20, Issue 2 , April 2020, , Page 58-73

Abstract
  The objective of this paper is to design a robust controller for a system modeled as a two-mass system, with a flexible coupling. Here, the flexible Joint between two-mass systems is characterized by a spring. In fact, a two-mass system represents most of an industrial drive, like rolling mill drives, ...  Read More ...

H2 Sliding Mode Controller Design for Mobile Inverted Pendulum System

Hazem I. Ali; Mustafa J. Kadhim

Volume 18, Issue 2 , September 2018, , Page 17-29

Abstract
  The design of an H2 sliding mode controller for a mobile invertedpendulum system is proposed in this paper. This controller is conducted to stabilizethe mobile inverted pendulum in the upright position and drive the system to adesired position. Lagrangian approach is used to develop the mathematical ...  Read More ...

Positively Invariant Sets in Sliding Mode Control Theory with Application to Servo Actuator System with Friction*

Dr. Shibly Ahmed AL-Samarraie

Volume 10, Issue 1 , December 2010, , Page 121-134

Abstract
  Abstract: In this paper two invariant sets are derived for a second order nonlinear affine system using a sliding mode controller. If the state started in these sets, it will not leave it for all future time. The invariant set is found function to the initial condition only, from which the state bound ...  Read More ...
