Multirate control is commonly used to improve the performance, or for increased computational efficiency of control systems. Multirate control system uses from two to many different rates of response based on various dynamic behaviors of decomposed subsystems. In this book, a set of models of multirate control systems with using the MATLAB for such different original systems as drones with coaxial rotor/ducted fan and vectored thrust configurations was used. All the considered models demonstrated good performance for more fast stabilization of multirate control systems in comparison with single-rate control systems, consequently, economy in battery energy usage for multirate control systems in comparison with original single-rate control systems can be achieved. This book is a valuable resource for all those interested in modeling of control systems for multirotor drones.

In today¿s world, the improved parameters of multirate control systems include the lasting impact on society such as energy economics. Multirate control system uses from two to many different rates of response based on various dynamic behaviors of decomposed subsystems. In this book the methods of mathematical model derivation in the state space for various subclasses of multirate multivariable control systems (i.e., multirate linear systems, multirate nonlinear systems, multirate stochastic systems) are developed. Methods for choice of periods of discretization for multirate multivariable discrete plants are offered. Numerous examples are given to demonstrate obtained results. These are the following models: the divided winding rotor synchronous machine, the boiler system, the two-tank level system, the mixer-tank system, the coaxial rotor/ducted-fan TUAV, the Lockheed L-1011 aircraft, the distillation column system, the plasma torch furnace system. All of these mathematical models are tested with the help of the Simulink software. The content of this book can be useful for researchers, academics, graduate and postgraduate students who are related with multirate control systems.
