SENSORS AND ACTUATORS
SENSORS AND ACTUATORSby Niell Elvin and Alex ElvinModern control systems are ubiquitous in mechanical engineering systems whether for the control of air-conditioning systems, aircraft landing gear, consumer and military drones or sophisticated robotic systems. A block diagram of a simplified feed-back control system is shown in Fig. 10.4.1. As can be clearly seen, the control system relies on actuators and sensors (details of the controller are covered in other chapters of this book). An actuator is defined as a mechanical system that is capable of producing mechanical work. A sensor or transducer is a system that is capable of detecting (i.e., measuring) a physical property (such as temper…
