On the prescribed-time attractivity and frozen-time eigenvalues of linear time-varying systems
Amir Shakouri
A system is called prescribed-time attractive if its solution converges at an arbitrary user-defined finite time. In this note, necessary and sufficient conditions are developed fo…
A Framework for Prescribed-Time Control Design via Time-Scale Transformation
Amir Shakouri, Nima Assadian
This letter presents a unified framework for the design of prescribed-time controllers under time-varying input and state constraints for normal-form unknown nonlinear systems with…
Prescribed-time control with linear decay for nonlinear systems
Amir Shakouri, Nima Assadian
In this letter, a new notion of stability is introduced, which is called triangular stability. A system is called triangularly stable if the norm of its state vector is bounded by…
Multiple-impulse orbital maneuver with limited observation window
Amir Shakouri, Seid H. Pourtakdoust, Mohammad Sayanjali
This paper proposes a solution for multiple-impulse orbital maneuvers near circular orbits for special cases where orbital observations are not globally available and the spacecraf…
Suboptimal Control of Unknown Second-order Nonlinear Systems with Guaranteed Global Convergence
Amir Shakouri, M. Reza Emami
A suboptimal active disturbance rejection controller (S-ADRC) is proposed for second-order systems with unknown time-varying nonlinear dynamics. The output-feedback controller guar…
Prescribed-time Control for Perturbed Euler-Lagrange Systems with Obstacle Avoidance
Amir Shakouri, Nima Assadian
This paper introduces a class of time-varying controllers for Euler-Lagrange systems such that the convergence occurs at an arbitrary finite time, independently of initial conditio…
