Robust optimal distance‐based formation control of uncertain nonlinear agents over directed topologies

open access: yesAsian Journal of Control, Volume 27, Issue 5, Page 2141-2157, September 2025.
Abstract This paper studies a formation control problem with distance constraints for nonlinear agents with uncertainties. Controlling an edge is assigned to only one of its incident agents. Directed graph theory is used to model the desired formation topology.

Maximum Dynamic Load Determination via a Novel Robust State‐Dependent Differential Riccati Equation

open access: yesIET Control Theory &Applications, Volume 19, Issue 1, January/December 2025.
ABSTRACT This paper presents a novel application of the differential form of the state‐dependent Riccati equation technique (SDRE) i.e., the state‐dependent differential Riccati equation (SDDRE) as an indirect solution to the robust tracking control (RTC) problem for determining maximum dynamic load.

An analytical adaptive optimal control approach without solving HJB equation for nonlinear systems with input constraints

open access: yesIET Control Theory &Applications, Volume 18, Issue 10, Page 1275-1288, July 2024.
The paper presents an analytical method to solve the optimal control problem for affine nonlinear systems with unknown drift dynamics. It introduces a new non‐quadratic cost function that considers input constraints and includes the cost of the feed‐forward component of the control law.

Approximate optimal control design for quadrotors: A computationally fast solution

open access: yesOptimal Control Applications and Methods, Volume 45, Issue 1, Page 85-105, January/February 2024.
Optimal motion planning of the quadrotor is investigated by using the newly developed finite time Θ‐D technique, which can provide a closed‐form state‐feedback suboptimal control law and has significant online computational efficiency. Those attributes facilitate online implementation of autonomous systems.
