As the demand for electric vehicles (EVs) is increasing nowadays, the need for customer-friendly, effective, and innovative solutions for charging is rapidly enhancing. The recent advancements in this direction not only include the fast and efficient charging mechanism but also the automation in the process. Frequent plugging in the EV’s charging cable to the socket maybe tiresome that can be overcome by robotic technology, where this repeated task can be done using autonomous mobile robots. This paper deals with a fully automated system of charging EVs via robots with V2X communication. Further, a supercapacitor-based fast and efficient charging method has been proposed, which can be adopted for the autonomous charging process to improve its effectiveness.

The aetiology for the development of temporomandibular disorders (TMDs) is multifactorial. This chapter deals with several controversies that exist regarding the role of occlusion as main etiological factor for TMDs with the evidence of numerous studies for and against the role of occlusion in TMD. Insights have been provided regarding various concepts of occlusion and its relation to the disorders of the temporomandibular joint.

Occlusal splints, where indicated, are vital for the treatment of temporomandibular joint disorders (TMDs). Use of occlusal splints for patients with TMDs is indicated to relieve any occlusal pressure causing uneven joint loading, reduce muscle pressure and symptoms of the joint disorders. There are various types of splints that are advocated to relieve TMD symptoms. Carefully selecting the type of splint and appropriate duration for usage of the splint therapy should be followed to achieve satisfactory results.

The section presents the numerical simulations of the open-loop OWC plant to identify the control problems associated with OWC plants.

The OWC system is usually constructed on the shoreline of the ocean, as shown in Fig. 2.1 (Mishra et al. 2016d). The OWC consists of four walls. It is open at the bottom where the ocean waves hit. The OWC chamber is partly watered, while the top part of the column is filled with air. The Wells turbine is installed in a circular cabinet at the top of the chamber and is driven by a DFIG connected to it. Based on rising and falling levels of seawater, the air in the chamber is compressed and decompressed. As a consequence, the oscillatory movement of the water causes the bidirectional airflow. Notwithstanding the alternating path of the airflow, the Wells turbine is constructed in such a manner that its rotation is always one-way. Next, mathematical models of ocean waves, OWC chamber, Wells turbine and DFIG are described.

This chapter deals with the MPPT control of OWC plant using rotational speed control. It is a very highly researched topic in OWC control. A large number of research papers have published in past three decades for rotational speed control of OWC plant.

In this chapter, the airflow control scheme for output power control of the OWC plant is presented. The control valves are used to regulate the airflow inside the OWC chamber. Several studies have discussed the airflow control techniques in the past three decades, e.g. Falcao and Justino (1999a), Falcao et al. (2003, 2010a), Amundarain et al. (2010b, 2011c), Alberdi et al. (2011a, b), Mishra et al. (2015). However, the anti-windup type PID and FOPID controllers are very simple to design and very effective in terms of OWC performance. Therefore, anti-windup PID and FOPID controllers have been designed with manual as well as optimal tuning approaches.
