DOWNLOAD EBOOK →Reduced-order predictors and models are then developed to facilitate rapid analysis and suitable control system design. Specific control philosophies are then discussed. Finally, the feedback control of stepper motors oftentimes relies heavily on costly sensing devices located in the rotor environment. It is the intent of this thesis to demonstrate that in the absence of such rotor signals, a stator signal, namely the dc link current, can be utilized to retrieve an estimate of the velocity perturbation. This allows for the application of the aforementioned control strategies using this estimate."

DOWNLOAD EBOOK →This book introduces a passivity-based approach which simplifies the controller design task for AC-motors. It presents the application of this novel approach to several classes of AC motors, magnetic levitation systems, microelectromechanical systems (MEMS) and rigid robot manipulators actuated by AC motors. The novel passivity-based approach exploits the fact that the natural energy exchange existing between the mechanical and the electrical subsystems allows the natural cancellation of several high order terms during the stability analysis. This allows the authors to present some of the simplest controllers proposed in scientific literature, but provided with formal stability proofs. These simple control laws will be of use to practitioners as they are robust with respect to numerical errors and noise amplification, and are provided with tuning guidelines. Energy-based Control of Electromechanical Systems is intended for both theorists and practitioners. Therefore, the stability proofs are not based on abstract mathematical ideas but Lyapunov stability theory. Several interpretations of the proofs are given along the body of the book using simple energy ideas and the complete proofs are included in appendices. The complete modeling of each motor studied is also presented, allowing for a thorough understanding. Advances in Industrial Control reports and encourages the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.

Recently, these motors have been used in situations which call for a large stepping rate; so large in fact, that the motor turns continuously. Although the equations which describe the stepper motor in this mode are decoupled, they are not time invariant. In order to eliminate the time varying terms, Park's transformation does not render the system equations time invariant, so an averaging technique is employed which does provide the desired time invariance. The averaged model is evaluated by comparing its dynamic response with that of a detailed simulation of the motor in a variety of operating modes. It is found that the averaged model does not adequately represent the motor dynamics under most operating conditions."

DOWNLOAD EBOOK →This book explores the direct thrust force control (DTFC) of tubular surface-mount linear permanent magnet synchronous motors (linear PMSMs). It presents a detailed account and analysis of several advanced nonlinear control schemes, based on the direct thrust control principle, to achieve a reduction in steady-state ripple in thrust force with faster transient response, and describes their experimental validation. It also provides rigorous details of the dynamic modelling of linear PMSMs from a control system perspective, and demonstrates the superior control performance of the proposed techniques compared to the current state-of-the-art techniques. Lastly, the book proposes and validates a stator flux observer for sensorless speed estimation comprising a linear state observer and an improved sliding mode component.
