On-line Traffic Signalization using Robust Feedback Control
… for more effective traffic signalization using robust feedback control methodology. Online traffic-responsive signalization is based on real-time traffic conditions and selects cycle, split, phase, and offset for the intersection according to detector data. A robust traffic feedback control …

Funnel libraries for real-time robust feedback motion planning
… within (despite bounded disturbances) when the feedback controller corresponding to the maneuver is executed. The resulting funnel library is then used to sequentially compose motion plans at runtime while ensuring the safety of the robot. A major advantage of the work presented here is that by …

Design of robust feedback control laws for high-dimensioned systems
The design of feedback control laws for discrete models of flexible structures is addressed. Two strategies are proposed. First, a parameter optimization method is used, in which the behavior of the controller is described by a performance measure and numerically optimized. A second method, based …

Detailed model for robust feedback design of main steam temperatures in coal fired boilers
… The main outcome of this project was to design a robust control system for a dynamic model of the boiler using sets of low order linear models to account for uncertainty. The main concepts, models and theories used in the development of this dissertation include: 1) A detailed thermo-fluid model …

A Framework for Controlling Quality of Sessions in Multimedia Systems
… layer. The first component is a scalable and robust feedback protocol, which allows for determining the worst case state among a group of receivers of a stream. This mechanism is used for controlling the transmission rates of multimedia sources in both cases of layered and single-rate …

Applied optimal control for dynamically stable legged locomotion
… which is able to quickly and reliably acquire a robust feedback control policy for 3D dynamic bipedal walking from a blank slate using only trials implemented on the physical robot. The robot begins walking within a minute and learning converges in approximately 20 minutes. The learning works …

Optimal placement of sensor and actuator for sound-structure interaction system
… acoustic cavity is used to construct a robust feedback controller based on minimax LQG control design method. The controller is aimed to reduce acoustic potential energy in the cavity. This energy is due to the structure-borne sound inside the sound-structure interaction system. …

Design and control of a self-sensing piezoelectric reticle assist device
… a novel charge-controlled amplifier with a more robust feedback circuit and a method for hysteresis compensation at DC. These technologies were key to achieving high-bandwidth high-precision sensorless force control. When tested with a trapezoidal force profile with 6400 N/s rate and 60 N peak …

Intelligent Flight Control Systems Using Adaptive Deep Neural Networks and Concurrent Learning-Based Design Methods
… <p>The second contribution presents a robust and adaptive DNN-based control method that formally compensates for unmodeled system dynamics in addition to actuator model uncertainty in a class of nonlinear, non-affine, overactuated dynamic systems. This result is inspired by recent …

Evacuation Distributed Feedback Control and Abstraction
In this dissertation, we develop feedback control strategies that can be used for evacuating people. Pedestrian models are based on macroscopic or microscopic behavior. We use the macroscopic modeling approach, where pedestrians are treated in an aggregate way and detailed interactions are …

An analysis of the emergence of adaptive governance for sustainable management of marine resources
… governance instruments and interventions, with robust feedback loops and mechanisms for learning across scales. To move beyond the limits of conventional planning and management, and transition to adaptive governance, an argument is therefore made for greater reflexivity in marine governance, in …
