The variable gain control method is a new construction technique for the control of nonlinear systems. By properly conducting state transformation that depends on the variable gains, the control design problem of nonlinear systems can be transformed into a gain construction problem, thus effectively avoiding the tedious iterative design procedure. Different from the classical backstepping method and forwarding design method, the structure of variable gain control is simpler in the sense that fewer design parameters are required, facilitating the improvement of system control performance. To highlight the learning, research, and promotion of variable gain control, Variable Gain Control and Its Applications in Energy Conversion is written based on the research results of peers at home and abroad and combining our latest research. This book presents innovative technologies for designing variable gain controllers for nonlinear systems. It systematically describes the origin and principles of variable gain control for nonlinear systems, focuses on the controller design and stability analysis, and reflects the latest research. In addition, variable gain control methods applied to energy conversion are also included. Discussion remarks are provided in each chapter highlighting new approaches and contributions to emphasize the novelty of the presented design and analysis methods. In addition, simulation results are given in each chapter to show the effectiveness of these methods. It can be used as a reference book or a textbook for students with some background in feedback control systems. Researchers, graduate students, and engineers in the fields of control, information, renewable energy generation, electrical engineering, mechanical engineering, applied mathematics, and others will benefit from this book.

In this thesis, we investigate the development of new control schemes for single- and three-phase boost-type converters and their application to energy conversion. The developed algorithms are utilized to efficiently convert energy from a source with an arbitrary voltage waveform to a DC link or a battery. This type of energy transfer is of great interest in energy conversion systems involving low frequency, time-varying input sources such as vibration energy harvesting and marine wave power. In such applications, the generated voltages are sporadic in the sense that the amplitudes and frequencies of the generated waveforms are time-varying and not known a-priori. Motivated by these applications, first a single-phase boost converter is studied and the performance of the proposed controller in providing a resistive input behavior is experimentally verified. Next, the idea proposed for a single-phase converter is extended to a three-phase bridgeless boost-type converter. To this end, an averaged model of the three-phase converter is obtained and utilized in designing a feedback control scheme to enforce a resistive behavior across each phase of the converter. Similar to the single-phase system, the proposed controller does not require a-priori knowledge of the input waveform characteristics and can convert waveforms with time-varying frequencies and amplitudes into DC power by regulating the input resistances at each phase. The proposed solution enables real-time variation of the generator loading using high efficiency switching power devices. Numerical simulations and experimental results are presented that evaluate performance of the proposed modeling and feedback control scheme for the three-phase system. Finally, an application involving energy regeneration for a mechanical suspension system is considered using a setup consisting of a mass-spring test rig attached to a mechanical shaker for single- and three-phase applications using a tubular DC permanent-magnet machine and rotary machine connected to an algebraic screw, respectively. The algebraic screw converts the translational motion of mechanical vibrations into rotary motion that acts as a prime mover for the three-phase synchronous machine. The experimental results reveal that the boost circuit and proposed feedback controller can successfully provide regenerative damping for mechanical vibrations with high-efficiency power conversion.

Inspired by the community behaviors of animals and humans, cooperative control has been intensively studied by numerous researchers in recent years. Cooperative control aims to build a network system collectively driven by a global objective function in a distributed or centralized communication network and shows great application potential in a wide domain. From the perspective of cybernetics in network system cooperation, one of the main tasks is to design the formation control scheme for multiple intelligent unmanned systems, facilitating the achievements of hazardous missions – e.g., deep space exploration, cooperative military operation, and collaborative transportation. Various challenges in such real-world applications are driving the proposal of advanced formation control design, which is to be addressed to bring academic achievements into real industrial scenarios. This book extends the performance of formation control beyond classical dynamic or stationary geometric configurations, focusing on formation maneuverability that enables cooperative systems to keep suitable spacial configurations during agile maneuvers. This book embarks on an adventurous journey of maneuverable formation control in constrained space with limited resources, to accomplish the exploration of an unknown environment. The investigation of the real-world challenges, including model uncertainties, measurement inaccuracy, input saturation, output constraints, and spatial collision avoidance, brings the value of this book into the practical industry, rather than being limited to academics.
