development and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولActive Noise Control in a Duct With Flow
Active noise control in a one dimensional acoustic duct, in which fluid medium inside the duct has a mean flow velocity, is studied. The acoustic duct model with general boundary conditions is solved in Laplace domain and infinite dimensional system transfer functions are obtained. For controller designs, appropriate microphone, and noise canceling source locations are determined. Low order fin...
متن کاملActive noise control of an acoustic duct using feedback control
Forced air cooling systems, such as an airconditioning system produce noise. For a pleasant living environment, this noise is undesirable. A way to suppress produced noise is reducing the sound in the duct where the air flows through afterwards. a his report handles the noise reduction in an active duct silencer by the use of a discrete feedback controller. Models of the involved processes are ...
متن کاملActive noise control of a duct using robust control theory
In this paper, the control of sound propagation in an air-handling duct is investigated. Employing identified discrete t ime models of the duct, robust linear controllers are designed using the combined pole placement/sensitivity function shaping method. T h e particularities of harmonic noise sources are taken into account, avoiding the classical stochastic adaptive and the reference noise bas...
متن کاملNonlinear active noise control in a linear duct
The problem in active noise control in a linear duct is examined. Essentially, a nonlinear inverse to a nonminimum phase actuator is proposed. The nonlinear inverse exploits the non-Gaussian nature of some chaotic and stochastic noise sources. The architecture of the controller is derived using Bayesian estimation theory and is shown to be a combination of a linear adaptive network and a radial...
