This paper deals with the identification of slowly time-varying system using Legendre basis functions. Physical phenomena exhibit time-varying behaviour for a number of reasons. To model these systems the models with time-dependent parameters are required. In this paper, the system with slowly varying parameters is considered for identification. The input to the time-varying system is chosen to be...
This paper deals with the use of Kalman filter approach for identification of linear fast time-varying processes. Most of the physical processes exhibit some degree of time-varying behavior. Physical processes exhibit time-varying behavior for a number of reasons. Some of the processes are inherently time-varying and can not effectively be modeled using time invariant models. Recursive identification...
Controller designs of multivariable systems are always difficult due to interactions and coupling between inputs and outputs. Control system design involves input/output (IO) selection, that is, decisions on the number, the place, and the type of actuators and sensors. The choice of inputs and outputs affects the performance, complexity, and cost of the control system. In most of the multivariable...
Automated steering control is a crucial element of vehicle automation. The California PATH Program at the University of California at Berkeley has developed one such system using magnetic markers embedded under the roadway for lateral guidance. This system was demonstrated during the August 1997 National Automated Highway System Consortium Feasibility Demonstration, San Diego, CA, without a single...
Speaker verification deals with the problem of verifying whether a given utterance has been pronounced by a claimed authorized speaker. This problem is important because an accurate speaker verification system can be applied to many security applications. Fundamental frequency is the rate of vocal folds vibration during speech. It is considered to be one of the most important prosodic features to...
