Speech-recognition rates decrease in noisy environments. The body-conducted speech, conducted in solids such as body and skins, has a noise-robust characteristics and can be served for recognition systems even in 98 dBSPL (-20 dBSNR) noise environments. However, the body-conduction can not capture high frequency sounds. Conventional methods to improve sound quality of body-conducted speeches need...
For precise control of tension and thickness in a tandem cold mill in acceleration and deceleration conditions, we employ a nonlinear model including the rolling speed as a time-varying parameter. It is demonstrated in simulation results that nonlinear receding horizon control by real-time optimization achieves satisfactory performance for the nonlinear model.
