Spacecraft Electromagnetic Docking and Separation in Elliptical Orbits solves problems for spacecraft electromagnetic docking and separation control system using different control methods: instead of the widely used proportional-integral-derivative controller or PID control. The book focuses on presenting a variety of control strategies tailored for spacecraft electromagnetic docking and separation, accompanied by stability proofs that integrate Lyapunov stability theory with sliding mode theory, LMIs-based theorems, model predictive control theories, reinforcement study theories and other frameworks, so the reader can understand how to handle different kinds of disturbances and perturbations in actual orbiting spacecraft. The book also provides a review of magnetic field, magnetic field force model (both the near-field model and the far-field model), useful lemmas and dynamic modelling methods of spacecraft relative motion, which can serve as first stage analysis for further research and are especially important in the initial design phase of a spacecraft electromagnetic docking and separation control systemA wide variety of novel robust and non-fragile controllers are discussed and against a backdrop of considering various uncertainties, e.g. advanced sliding mode control, observer-based control, model predictive control, reinforcement study-based control and impedance control; these are not only applicable to spacecraft electromagnetic docking and separation control, but also easily extendable to a more general class of second-order system with uncertainties and perturbationsDiscusses the mathematical representation of spacecraft electromagnetic docking and separation control systems with uncertainties embedded in them leads to a model-like continuous and discrete state-space form which makes the developed controller universalDiscusses the role, in spacecraft electromagnetic docking and separation, of how the control systems in achieving high-precision position and better robustness to external disturbances (plus various uncertainties and gain perturbations) can be achieved
