Abstract Shallow-water sloshing motions in a three-dimensional rectangular tank are investigated. The Boussinesq-type equations terms of velocity potential and the finite-difference scheme applied for solutions numerical model. Through linking rate decay wave amplitudes to energy dissipation due friction at walls, linear damping term is proposed added into free surface boundary condition. Takin...

This paper introduces a 2 0 visual servoing technique for the station keepiirg of an unmanned underwater vehicle (UUV) with respect to planar targets on the sea bed. The underwater vehicle is subject to sea current disturbances which make it drift from its desired position. Feature points from unmarked objects are extracted and tracked with a sparse feature tracker developed in-house [I]. The s...

The present paper describes the development of an indirect adaptive fuzzy control scheme employing feedback linearizing technique. The scheme proposes the development of a fuzzy certainty equivalence controller for controlling non-linear plants. This controller is designed on the basis of plant parameccepted 3 January 2011 vailable online 11 January 2011 eywords: ndirect adaptive control ters e...

This paper provides a systematic approach for the design of buffer tanks. We consider mainly the case where the objective of the buffer tank is to dampen (“average out”) the fast (i.e., high-frequency) disturbances, which cannot be handled by the feedback control system. We consider separately design procedures for (I) mixing tanks to dampen quality disturbances and (II) surge tanks with averag...

Abstract: The present paper introduces a control oriented model based on air and burned gas flows for automotive engines with variable valves. Moreover, a predictive controller is proposed by using the obtained model. For the engines with variable valves, the intake valve lift enables the quick torque response; on the other hand, the large valves’ overlap may cause a misfiring of combustion bec...

Metal oxide surge arresters (ZNO) are used widely in power system to protect equipments from over voltages. Non uniform potential distribution leads to the depressed service life and low safe reliability, so grading ring is applied on HV surge arrester order to uniform the electric field distribution. One of the problems of arresters is leakage current in power frequency that different paramet...

It is well known that flow instabilities called rotating stall and surge may occur in non-cavitating turbomachines at flow rates smaller than design. Rotating stall is a local instability at the turbomachinery which is basically not dependent on the hydraulic system in which the turbomachine is installed. The stalled region rotates faster than impeller. Surge is a system instability in a hydrau...
