Book Synopsis Dynamic Modelling and Nonlinear Control of Vortex-coupled Delta Wing Systems by : Mehrdad Pakmehr

Download or read book Dynamic Modelling and Nonlinear Control of Vortex-coupled Delta Wing Systems written by Mehrdad Pakmehr. This book was released on 2005. Available in PDF, EPUB and Kindle. Book excerpt: The first part of this thesis proposes a control-oriented vortex-coupled nonlinear retarded state space representation of free-to-roll motion of a delta wing. Linear, nonlinear and neural network based parameter identification methods have been used to approximate the rolling moment coefficient. Various experimental results validate the proposed model. In the second part, fast vortex-coupled delta wing roll dynamics with state delay in is controlled using a robust adaptive output feedback control law. The controller has been tested against modelling uncertainties in rolling moment coefficient. The controller is shown to render the delta wing vortex-coupled roll dynamics globally practically stable. Heuristic design process and parameter selection methods have been proposed for easier implementation of this control algorithm. The results of the numerical simulation demonstrate the applicability of this controller for different initial conditions. The third part proposes a combinatory control strategy combined of a modified state feedback stabilizing controller, as the internal loop, and a robust adaptive sliding tracking controller. The robust adaptive tracking controller utilizes a special gaussian radial basis function network for online estimation of unknown nonlinearity. To show the capability of the proposed combinatory control structure, it has been implemented to the delta wing dynamics to follow a complex reference trajectory. Implementing the proposed combined control structure enhanced the tracking performance in comparison to the controller without internal loop. Adding two more control inputs enhanced the tracking controller performance. The Heuristic design process and parameter selection methods have been proposed for easier implementation of tracking control and combined control structure.

Book Synopsis Linear Parameter-Varying and Time-Delay Systems by : Corentin Briat

Download or read book Linear Parameter-Varying and Time-Delay Systems written by Corentin Briat. This book was released on 2014-09-03. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an introduction to the analysis and control of Linear Parameter-Varying Systems and Time-Delay Systems and their interactions. The purpose is to give the readers some fundamental theoretical background on these topics and to give more insights on the possible applications of these theories. This self-contained monograph is written in an accessible way for readers ranging from undergraduate/PhD students to engineers and researchers willing to know more about the fields of time-delay systems, parameter-varying systems, robust analysis, robust control, gain-scheduling techniques in the LPV fashion and LMI based approaches. The only prerequisites are basic knowledge in linear algebra, ordinary differential equations and (linear) dynamical systems. Most of the results are proved unless the proof is too complex or not necessary for a good understanding of the results. In the latter cases, suitable references are systematically provided. The first part pertains on the representation, analysis and control of LPV systems along with a reminder on robust analysis and control techniques. The second part is concerned with the representation and analysis of time-delay systems using various time-domain techniques. The third and last part is devoted to the representation, analysis, observation, filtering and control of LPV time-delay systems. The book also presents many important basic and advanced results on the manipulation of LMIs.

Book excerpt: The sliding mode control paradigm has become a mature technique for the design of robust controllers for a wide class of systems including nonlinear, uncertain and time-delayed systems. This book is a collection of plenary and invited talks delivered at the 12th IEEE International Workshop on Variable Structure System held at the Indian Institute of Technology, Mumbai, India in January 2012. After the workshop, these researchers were invited to develop book chapters for this edited collection in order to reflect the latest results and open research questions in the area. The contributed chapters have been organized by the editors to reflect the various themes of sliding mode control which are the current areas of theoretical research and applications focus; namely articulation of the fundamental underpinning theory of the sliding mode design paradigm, sliding modes for decentralized system representations, control of time-delay systems, the higher order sliding mode concept, results applicable to nonlinear and underactuated systems, sliding mode observers, discrete sliding mode control together with cutting edge research contributions in the application of the sliding mode concept to real world problems. This book provides the reader with a clear and complete picture of the current trends in Variable Structure Systems and Sliding Mode Control Theory.

Book excerpt: In the formation of any control problem there will be discrepancies between the actual plant and the mathematical model for controller design. Sliding mode control theory seeks to produce controllers to over some such mismatches. This text provides the reader with a grounding in sliding mode control and is appropriate for the graduate with a basic knowledge of classical control theory and some knowledge of state-space methods.
