Vehicular Applications of Koopman Operator Theory -- A Survey

no code implementations18 Mar 2023 Waqas Manzoor, Samir Rawashdeh, Alireza Mohammadi

Koopman operator theory has proven to be a promising approach to nonlinear system identification and global linearization.

Integral Line-of-Sight Curved Path Following of Helical Microswimmers Actuated by Rotating Magnetic Dipoles

no code implementations5 Jun 2022 Alireza Mohammadi, Mark W. Spong

This short paper investigates the problem of curved path following for helical microswimmers actuated by rotating magnetic dipoles.

Chetaev Instability Framework for Kinetostatic Compliance-Based Protein Unfolding

no code implementations15 May 2022 Alireza Mohammadi, Mark W. Spong

Understanding the process of protein unfolding plays a crucial role in various applications such as design of folding-based protein engines.

Generation of Wheel Lockup Attacks on Nonlinear Dynamics of Vehicle Traction

no code implementations16 Dec 2021 Alireza Mohammadi, Hafiz Malik, Masoud Abbaszadeh

This paper demonstrates that the adversary despite having a limited knowledge of the tire-road interaction characteristics has the capability of driving the states of the vehicle traction dynamics to a vicinity of the lockup manifold in a finite time by means of a properly designed attack policy for the frictional brakes.

Location-aware Beamforming for MIMO-enabled UAV Communications: An Unknown Input Observer Approach

no code implementations20 Nov 2021 Alireza Mohammadi, Mehdi Rahmati, Hafiz Malik

Numerous communications and networking challenges prevent deploying unmanned aerial vehicles (UAVs) in extreme environments where the existing wireless technologies are mainly ground-focused; and, as a consequence, the air-to-air channel for UAVs is not fully covered.

Integral Line-of-Sight Path Following Control of Magnetic Helical Microswimmers Subject to Step-Out Frequencies

no code implementations29 Apr 2021 Alireza Mohammadi, Mark W. Spong

Due to the embedded integral action in the reference vector field, the microswimmer will follow the desired straight line by compensating for the drift effect of the environmental disturbances as well as the microswimmer weight.

Quadratic Optimization-Based Nonlinear Control for Protein Conformation Prediction

no code implementations27 Apr 2021 Alireza Mohammadi, Mark W. Spong

The resulting kinetostatic control torque inputs will be close to the KCM-based reference vector field and guaranteed to be constrained by a predetermined bound; hence, high-entropy-loss routes during folding are avoided while the energy of the molecule is decreased.
