Using this method to assign the poles of system, only one output and only one input in system are used to create the feedback controller.

Due to its simplicity, the combination of an orifice plate and differential pressure transmitter is widely used for flow measurement in process industries. However, one problem with this method is that the process connection of the DP transmitter is easily blocked by congealed fluid, or by accumulations of impurities from the fluid. At present, plant operators deduce that there is a blockage of the process connection based on their experience and intuition, when they observe abnormal output signals. If a blockage could be detected before the transmitter output signals become abnormal, it would improve the plant control. Usually the fluctuating \"noise\" component of process pressure is removed by a low-pass filter in the signal processing circuits of the transmitter. However, we found that this \"noise\" could be used to detect blockage of the process connection.","PeriodicalId":344374,"journal":{"name":"SICE '95. Proceedings of the 34th SICE Annual Conference.

Tracking filters are discussed from the viewpoint of the fundamental problems of both modeling accuracy and real-time computational requirements. In most cases, if one becomes better, another gets worse. A trade-off between them always exists. Then our algorithm satisfies these conditions as much as possible by use of coupled filters. Through several simulations, validity of our algorithm has been confirmed in tracking non-maneuvering target.","PeriodicalId":344374,"journal":{"name":"SICE '95.

The first problem is to determine the control strategy so that the robot describes the shortest trajectory linking an arbitrary position inside a working area and a right-line path to be followed. This problem is solved by considering an equivalent minimum-time nonlinear control problem. The control switching functions which minimize the Hamiltonian function of the minimum-time control problem has been determined in a general form. The second problem analyzed consists in designing a nonlinear observer for the dynamic estimation of the variables required to implement the shortest-trajectory control strategy. A Luenberger-like nonlinear observer was designed. It was found that the observer estimates fastly enough the state variables of the mobile robot so that path tracking can be efficiently implemented.","PeriodicalId":344374,"journal":{"name":"SICE '95.

Two iterative reconstruction algorithms based on optimization of the Newton-Raphson method and finite element method were used to reconstruct the resistivity and permittivity distribution. These algorithms iteratively minimize the objective function to find the solution. To reconstruct the internal resistivity and permittivity distribution, the finite element model is constructed in complex field of resistive and capacitive medium.
