This book provides a simplified description of how to design an underwater swimming robot, inspired by the mechanism of the Labriform mode of fish. This style of swimming depends on the pectoral fins only as a main locomotor for movement. A unique model with fins having a concave shape allows the highest thrust force to be achieved during the power period and the lowest drag force during the recovery period, especially if the velocity values between the powering and recovery periods are manipulated.Besides the ability to swim quickly, the proposed model was also inspired by a method of maneuvering based on the principle of differential drive for two-wheel mobile robot, achieving the minimum turning radius by controlling the speed of the rowing fins.Also, by applying the technique of the diving model used by gliders, the robot achieves underwater gliding by changing the center of the body's mass. Thus, the robot obtains the ability to dive and float in a manner similar to the Sawtooth wave.All the mentioned tasks were conducted via laboratory experiments and proven to be both effective and efficient.

This book comprises ten invited expert contributions on the theory and applications of genetic algorithms in a variety of engineering systems. In addition to addressing the simple formulation of GAs, the chapters include original material on the design of evolutionary algorithms for particular engineering applications.

This book focuses on a class of uncertain systems that are called imperfect, and shows how much systems can regularly work if an appropriate control strategy is adopted.

It is well known that FOS can be applied in control applications and systems modeling, and their effectiveness has been proven in many theoretical works and simulation routines. This book aims to propose implementations and applications of Fractional Order Systems (FOS).
