Linear Control of Unmanned Aerial Vehicles
… workflow for the modeling, identification, and control of quadrotor unmanned aerial vehicles (UAVs) operating in windy conditions, covering the complete process from raw data-driven model development to advanced control design and experimental validation. The study begins by introducing a …

A Robotic Head Stabilization Device for Post-Trauma Transport
… device. Following testing with a simple PID controller, it was determined an advanced feedback controller with disturbance rejection capabilities was required. Linear Active Disturbance Rejection Control (LADRC) was chosen for its effectiveness in rejecting perturbations and handling modeling …

Adaptive Control Methods for Non-Linear Self-Excited Systems
… resulting limit cycle is induced by any slight disturbance that causes the response of the system to grow to the saturation level of the nonlinearity. Because there is no external disturbance, control of these self-excited systems requires that the open loop system dynamics are altered so that …

Discrete-time Contraction Analysis and Controller Design for Nonlinear Processes
… smart plants). This warrants the development of control systems for nonlinear chemical processes to be capable of tracking time-varying setpoints to produce products with different specifications as per market demand and deal with variations in the raw materials and utility (e.g., energy). This …

Application of modern control techniques to a distillation column
Modern control techniques have been applied to a distillation column. Three control techniques were selected for evaluation. These are; a decoupling and disturbance rejection control scheme; an estimator aided control techniques using a Kalman filter; and an implicit generalised minimum variance …

Traversability Estimation Techniques for Improved Navigation of Tracked Mobile Robots
… this dissertation proposes the use of an active disturbance rejection controller. The proposed controller is capable of estimating and counter acting the effects of slip in real-time to improve trajectory tracking. As an extension of the above application, this dissertation also proposes the use …
