Attitude and Vibration Control of a Flexible Spacecraft Using Hybrid Adaptive Super-Twisting Non-Singular Terminal Sliding Mode Control

Valiollah Shahbahrami; Milad َAzimi; َAlireza Alikhani

Volume 16, Issue 4 , December 2023, , Pages 1-13

Abstract
  In this paper, a robust adaptive hybrid control approach based on a combination of super-twisting and non-singular terminal sliding mode control (STNSMC) approaches for vibration and attitude control of a flexible spacecraft with fully coupled dynamic is developed. The proposed adaptation law eliminates ...  Read More

A New Backstepping Sliding Mode Guidance Law Considering Control Loop Dynamics

Vahid Behnamgol; Ahmad Reza Vali; Ali Mohammadi

Volume 8, Issue 4 , January 2016, , Pages 9-17

Abstract
  In this paper, a new procedure for designing the guidance law considering the control loop dynamics is proposed. The nonlinear guidance loop entailing a first order lag as the control loop dynamics is formulated. A new finite time and smooth backstepping sliding mode control scheme is used to guarantee ...  Read More
