Novel path loss and delay spread models with antenna height dependency under indoor stair environment are proposed. According to the persons' posture and location of the mobile device, the antenna height is categorized as three levels: low, medium and high. The path loss is modeled by using minimum mean square error (MMSE) method; meanwhile, both of mean excess delay and RMS delay spread are modeled...
This paper is an extension for impulsive control of nonlinear systems without time delay. According to impulsive control scheme, we establish impulsive model of nonlinear systems with time-varying delays. By utilizing the methods of Lyapunov functions and impulsive-type comparison principles, we obtain a general conditions under which impulsively controlled nonlinear systems with time-varying delays...
A nonlinear active disturbance rejection controller (ADRC) for finishing automatic width control (FAWC) system was proposed to improve the accuracy of strip width. The corresponding ADRC parameters were tuned by using the chaos optimization method. In order to produce the fast transient response of the time-delay system, the proposed ADRC consists of the extended state observer (ESO) and the nonlinear...
