In this chapter we present the application of the optimization method using bee colony (BCO for its acronym in English, Bee Colony Optimization), for optimizing fuzzy controllers, BCO is a heuristic technique inspired by the behavior of honey bees in the nature, to solve optimization problems. This was tested in two BCO optimization problems, one optimized set of mathematical functions for twenty to fifty dimensions, and two fuzzy controllers' optimization. The results are compared with other bio-inspired algorithms state of the art, of which we highlight that there is a lot of competition in terms of quality and consistency in the results, even if the method is one of the latest in the field of collective intelligence. Similarly presents some interesting observations derived from observed performance.

In this chapter, we present a study of numerical simulation of centerline velocity, velocity contour and wall shear stress for a two dimensional viscous and incompressible fluid flow in rectangular pipe. The numerical results have been corroborated through a scaling law and asymptotic analysis. It deals with simulation of viscous flow in a typical hydraulic control system can be used in Electro Optical Tracking System (EOTS). Due to geometric constraint, the typical piping can be used in hydraulic circuit of EOTS is of rectangular (with aspect ratio p factor = 1) cross section. The two dimensional governing equation of laminar flow of highly viscous fluid is solved in the present work by using finite difference method. Through extensive simulation, the grid independence of centerline velocity and wall shear stress has been established in the present study. In addition a scale analysis approach and asymptotic analysis of the problem have been carried out. The axial velocity profile in 3D space and corresponding contour has been computed here. It has been demonstrated that the velocity contour is parabolic in nature. The present work also establishes the fact that the velocity profile remains parabolic for rectangular pipe with varying cross sectional aspect ratio (p factor). At different p factor, the centerline velocity and wall shear stress have also been presented in this chapter.

The charging station of battery replaceable EV is used as measures for voltage control for a distribution network with large penetration of PVs. Stochastic optimal operation method of the charging station which maintains voltage of a distribution network and can replace batteries is studied. In addition, the battery usage fee is evaluated to get incentive to both EV users and the charging station to demonstrate usefulness of battery replaceable EV.

A general outline of the ESPC coupled atmosphere/ocean/ice/wave/land prediction system is proposed for the Initial Operational Capability targeted for 2018. A description of how it will cycle at both FNMOC and NAVOCEANO is included, although the specifics of how the distributed job control will function are still to be determined as the system becomes more mature. A potential issue with regard to the transfer of model output between the two centers has been identified and must be addressed in the upcoming years.

Many studies on human support robots have been carried out hitherto. The bilateral control based on 4ch bilateral controller is an efficient method for human support. Bilateral control is a method for realizing transmission of force sensation between a master system and a slave system. However, in the case of a multi-degree of freedom system, containing vertical motion, it is difficult to distinguish reaction force and gravity force. Moreover, it is difficult to actuate multi-degree of freedom robots with direct drive motors because the rating of motors are limited. The mechanical gravity canceller is one of the best solutions for gravity compensation. This mechanism uses compression springs and slider crank mechanisms to suppress the gravity torque. However, only a static model has been built up to now. Therefore, this paper presents a dynamic model based on Newton-Euler and Euler-Lagrange equations. Through this model and experimental results, no effect of springs are shown during motion control.

Haptic transmission using bilateral control is used not only for tele-operation of robotic systems but also for extraction and reproduction of human motions. Popularization of the haptic technology causes growing concern about increase in the amount of haptic data of human motions. This study clarifies that conventional bilateral control is equivalent to equilibrium force control of impedance control. In other words, haptic transmission can be realized only by using information of the equilibrium force. The validity of the proposed force-based approach is verified by simulations. The obtained results show the proposed approach achieves the same performance comparing with conventional approach, which requires to transmit position, velocity, and force information. This result shows that the proposed approach succeeded to decrease the amount of haptic data without any shortcomings.

In this chapter we study the automatic design of type-2 non-singleton fuzzy logic controller. To test the controller we use an autonomous mobile robot for the trajectory tracking control. We take the basis of the interval type-2 fuzzy logic controller of previous work for the extension to the type-2 non-singleton fuzzy logic controller. A genetic algorithm is used to obtain an automatic design of the type-2 non-singleton fuzzy logic controller (NSFLC). Simulation results are obtained with Simulink showing the behavior of the mobile robot whit this type of controller.

This chapter illustrates how to set up an inexpensive but effective Hardware-in-the-Loop (HIL) platform for the test of wind turbine (WT) controllers. The dynamics of the WT are simulated on the open-source National Renewable Energy Laboratory WT simulator called FAST (Fatigue, Aerodynamics, Structures, and Turbulence), which emulates all required input signals of the controller and reacts to the controller commands (almost) like an onshore real turbine of 5 MW. The dynamic torque control system runs on an open hardware Arduino microcontroller board, which is connected to the virtual WT via USB. In particular, the power generation control in the full load region for variable-speed; variable-pitch wind turbines is considered through torque and pitch control. The HIL proposed platform is used to characterize the behavior of the WT in normal operation as well as in fault operation. In particular, a stuck/unstuck fault is modeled and the behavior of a proposed chattering torque controller is analyzed in comparison to a baseline torque controller.
