چکیده
control is less reliable than wired control due to packet loss, time delay, and packet disorder caused by wireless communication. A Bernoulli random process was used to model the possible packet loss. A modi ed LQG control with a disturbance observer (DOB) was proposed to control the cRSEA under packet loss [1]. Under the situation when future references can be previewed, the preview control technique was extended so that the previewed reference signal can be used for improved tracking performance [2]. To deal with time-varying delays, a communication disturbance observer (CDOB) was investigated [3]. A wireless control system was built using WirelessHART protocol to test the performance of proposed controllers [4].

متن کاملAn overview of scanning near-field optical microscopy in characterization of nano-materials
Scanning Near-Field Optical Microscopy (SNOM) is a member of scanning probe microscopes (SPMs) family which enables nanostructure investigation of the surfaces on a wide range of materials. In fact, SNOM combines the SPM technology to the optical microscopy and in this way provide a powerful tool to study nano-structures with very high spatial resolution. In this paper, a qualified overview of ...
