摘要：Control system design packages like MATLAB, MATRIXX, Control C, SIMNON, etc. have become essential ingredients of both undergraduate and graduate courses in the fields of systems and controls. The use of MATLAB and its companion toolboxes in teaching graduate and undergraduate courses was reported by many educators in the past. The experience with the use of SIMULINK and MATLAB in Intelligent Control Course is introduced which is offered to graduate students at Beijing University of Aeronautics and Astronautics （BUAA）. The use of SIMULINK for simulation of intelligent control of their behavior is emphasized. The MATLAB features useful in this course are presented. How SIMULINK and MATLAB help in enhancing the students＇ understanding of the material and reducing the amount of time spent in performing computational homework assignments is discussed.

摘要：Introducing basic design methodology for developing backstepping nonlinear controller for vibration control system. With a simplified second-order system model of nonlinear vibration system （Duffing＇s equation）, where, the process has illustrated the backstepping design step-by-step. Backstepping is a novel nonlinear design tool, which is based on constructing the Lyapunov function for the closed-loop systems and guarantees the stability and tracking performance through energy dissipation. In general, this nonlinear control design approach generates aggressive control effort to reduce the tracking error presented in this control system and significantly improve the system bandwidth. The effectiveness of the design scheme is shown through the computer simulation.

摘要：Based on the sensing mechanism of microsensor, a simulation model of a practical silicon beam resonator attached to an E-type round diaphragm and used for measuring concentrated force is established. The relationship between the basic natural frequency of the beam resonator and the concentrated force is calculated, analyzed and investigated. As a microsensor FEM is used to study some important simulation results on the vibration features of the beam resonators. Based on the differential output signals, a set of optimum parameters of the proposed sensing unit is determined.

摘要：Micro and Nano technology are engineering on an extremely small scale. Already they are being applied to create many new products. Nanotechnology is predicted to become the basis for remarkably powerful and inexpensive computers, fundamentally new medical technologies that could save millions of lives, sensors important in military application as well as environmental protection. The main aim of this review is to concentrate information from different printed and online sources and help to make a right decision in very dynamic sensor market as well as let know what we should expect in the nearest future.
