This paper proposes the work on the back stepping controller for the class of Discrete-time nonlinear system under amplitude & rate saturation, dead-zone constraints. A robust adaptive neural network (NN) control is developed for a general class of uncertain single-input-single output (SISO) discrete time nonlinear system with unknown system dynamics and input nonlinear ties. Here ( ) function...
There are two types of system, one is linear and another one is nonlinear. For the control of linear systems there are several methods. Linear control theory is not directly applicable on nonlinear systems and there are so many approximations if linear control theory is directly applied on nonlinear systems. There is no unique method for analyzing nonlinear systems. A back stepping like design approach...
In this paper, an-LMI approach is utilized for the stabilization of Discrete-Time Delay Nonlinear Systems (DTDNS). The delay provided is state-delay. The control criterion is derived in terms of linear matrix inequalities (LMI's). The controller is designed by making use of back stepping technique. By choosing an appropriate Lyapunov function, some mathematical manipulations have been carried out...
This paper proposes a back stepping controller for the class of discrete-time nonlinear system in the presence of input nonlinearities like saturation and dead-zone. A robust adaptive neural network (NN) control is investigated for a general class of uncertain single-input-single-output (SISO) discrete-time nonlinear systems with unknown system dynamics and input nonlinearities i.e. combination of...
This paper proposes the adaptive back stepping controller for a class of nonlinear discrete-time systems in strict-feedback form with unknown dead-zone using neural networks. The control design is attained by introducing the dead-zone nonlinearity and using it in the controller design with back stepping technique. A dead-zone inverse is developed to compensate the dead-zone effect in nonlinear systems...
The high peak-to-average power ratio (PAPR) of the transmit signal is considered to be one of the major drawback of OFDM (orthogonal frequency division multiplexing) systems. The peak transmitted power can be substantially larger than that of a single carrier system. PTS (partial transmit sequence) can improve the peak-to-average power ratio (PAPR) statistics of an OFDM signal. In this paper, we have...
