The robustness of dynamical systems against external perturbations is crucial in engineering; however, it is often overlooked for the lack of methods for rapidly computing it. This paper proposes a novel algorithm for estimating the robustness of systems subject to time delay. More precisely, the algorithm iteratively estimates the so-called local...

A simplified mechanical model of vehicle towing is constructed. The towing procedure is modeled by means of two blocks connected with a linear spring that represents the elastic drawbar. The driver in the towing car controls the velocity of towing, while the driver of the towed vehicle tries to maintain a constant tension in the drawbar. Both contr...

The present work investigates the dynamics of a guided control situation when an automated vehicle is traveling in front of a human-driven vehicle, while the control of the automated vehicle contains the combination of a cruise control term and a backward looking term. The plant and string stability conditions of the underlying dynamical system are...

The paper investigates the nonlinear dynamics of the collocated position control of a trolley that carries a pendulum. Delayed proportional derivative control force is considered, which is based on the position and velocity of the trolley only. Stability charts are constructed for different parameter combinations, which show intricate structures in...

This paper investigates the dynamics of a fuzzy controlled polishing machine where the effect of temporal sampling is also taken into account. Chaotic and transient chaotic behaviors are experienced for certain control parameter combinations. In the case of transient chaotic motion, closed-form algebraic expressions are determined for the expected...

The interference of the elasticity of a single robotic arm and the unavoidable time delay of its position control is analysed from nonlinear vibrations viewpoint. The simplified mechanical model of two blocks and a connecting spring considers the first vibration mode of the arm, while the collocated proportional-derivative (PD) control uses the sta...

Because of the finite reaction time of human drivers, the towing process of a broken-down vehicle can often lead to unwanted oscillations. The paper presents a mechanical model of vehicle towing, where the driver of the first car tries to keep a constant velocity, while the driver of the towed vehicle uses the brakes to maintain a desired force in...

The stability of the collocated position control of a mass is studied when a pendulum is attached to it. The simplest proportional-derivative (PD) controller is applied, but the relevant constant time delay is taken into account. The linearized governing equations of the system are investigated. Stability charts are constructed for different pendul...
