ABSTRACT
The integration of electric actuating systems (AC, DC, and stepper motors; control valves; heaters; solenoids; etc.) with mechanical (e.g., belts and screw wheels.), fluidic (pumps), or thermal transmission elements enables us to drive actions related to the dynamics of solid, liquid, and gas material or chemical reactions. In this chapter, classical dynamics models for electrical-driven actuating systems are presented, along with their associated transmission element dynamics. In addition, their technical specifications, control strategies, and computer interface requirements are covered. Then, a methodology for the sizing and selection of those actuating systems is developed, based on their operating characteristics (e.g., torque–speed curves and load profile) and respective applications. Similarly, binary actuators and nanodevices, such as electroactive polymers, piezoactuators, shape alloys, and solenoids, are technically described and modeled. Eventually, the modeling of some products (e.g., high-speed trains and solar-based heating systems) and processes (e.g., handling processes through a seaport gantry) is covered to illustrate real-life applications.
