Wing Rock Modeling and Control for Flight-Critical Systems
Eugene Lavretsky, Miroslav Krstic
Aircraft equipped with delta wings are designed to be aerodynamically efficient in high-speed flight. However, at low-speed flight conditions with sufficiently high angle of attack…
Control of Flight
Eugene Lavretsky
The main focus of this talk is to present mathematical fundamentals, state-of-the-art, technical challenges and open problems in control of flight for atmospheric vehicles, such as…
Output Feedback Control of Linear Time-Invariant Systems with Operational Constraints
Marcel Menner, Heather Hussain, Eugene Lavretsky
This paper introduces a systematic method for designing robust linear controllers using output feedback in the presence of operational constraints. The design uses Nagumo's Theorem…
State Feedback Controllers with Operational Constraints
Eugene Lavretsky
In this paper, a state feedback control design with min/max operational limiting constraints is developed for multi-input-multi-output linear time invariant systems. Specifically,…
Modeling Unsteady Aircraft Aerodynamics Using Lorenz Attractor: A Reduced-Order Approach for Wing Rock
Marcel Menner, Eugene Lavretsky
This paper presents a novel modeling approach for unsteady aircraft airflow, leveraging the Lorenz attractor framework. The proposed model is based on the force distribution exerte…
Robust Linear Design for Flight Control Systems with Operational Constraints
Marcel Menner, Eugene Lavretsky
This paper presents a systematic approach for designing robust linear proportional-integral (PI) servo-controllers that effectively manage control input and output constraints in f…
Compatibility of Multiple Control Barrier Functions for Constrained Nonlinear Systems
Max H. Cohen, Eugene Lavretsky, Aaron D. Ames
Control barrier functions (CBFs) are a powerful tool for the constrained control of nonlinear systems; however, the majority of results in the literature focus on systems subject t…
Servo-Controllers with Operational Constraints
Eugene Lavretsky
In this paper, a proportional-integral servo-control design method is developed for multi-input-multioutput linear time invariant systems with operational constraints imposed on th…
Integrator Anti-Windup Design for Servo-Controllers with Position Constraints
Eugene Lavretsky
A control design modification to prevent integrator windup for position saturated servo-controllers is introduced. The design is based on the formalism of Control Barrier Functions…
Translation of Nagumo's Foundational Work on Barrier Functions: On the Location of Integral Curves of Ordinary Differential Equations
Marcel Menner, Eugene Lavretsky
In 1942, Prof. Mitio Nagumo published his seminal paper on the location of integral curves of ordinary differential equations. Nagumo's paper provides the foundation of the set inv…
