Measurement and Control Systems with Smart Sensor and Actuators in Industrial LAN Environment

چکیده
Smart sensors and actuators, industrial nets (ILAN) and program support SCADA/MMI software on the environment of PC computers introduces importance alternatives to implementation of modern configured multilevel measurement and control systems. The paper describes implementation of smart sensors (SS) at the distributed measurement and control systems (DMCS).To the main advantages of smart sensors belong: compact form with common supply and standard output signals, with good functionality at hard conditions, minimisation and compensation of the disturb influence to measuring transducers and to the output signal (temperature influence, static characteristic non-linearity, transfer disturbing), local signal processing with duplex communication, function testing and data validation. Some results will be present with design, structure and properties of displacement smart sensors with two types of optical fiber transducers. These subsystems are interconnected with microcomputers and controllers by ILAN with SCADA/MMI program support that enable to reach very good functional parameters with higher flexibility, reliability, testing and maintenance.

In this paper, the active buckling control of smart functionally graded (FG) plates using piezoelectric sensor/actuator patches is studied. A simply supported FG rectangular plate which is bonded with piezoelectric rectangular patches on the top and/or the bottom surface(s) as actuators/sensors is considered. When a constant electric charge is imposed, the governing differential equations of mo...
