This work concerns the synthesis of discrete-time nonlinear controllers for nonlinear processes that make the closed-loop system linear in an input/output sense. The synthesis of state feedback controllers is studied first, followed b.y the synthesis of dynamic output feedback controllers. Both problems are solved within the globally linearizing control ( GLC) framework. Precise theoretical con...

this paper concerns a study on the optimal control for nonlinear systems. an appropriate alternative in order to alleviate the nonlinearity of a system is the exact linearization approach. in this fashion, the nonlinear system has been linearized using input-output feedback linearization (iofl). then, by utilizing the well developed optimal control theory of linear systems, the compensated nonl...

The purpose of this paper is to design and analyze feedback control laws achieving output linearization for wheeled mobile robots models taking into account small slipping effects at the wheel/ground contact point. We discuss the existence and attractivity of the slow manifold associated to any feedback control, and we show the existence of a feedback control law that achieves output linearizat...

This paper presents results of investigation on the effects of technology on the performance of the class E power amplifier circuit. A typical class E circuit has been designed and simulated, for a typical UMTS Tx frequency (1.95 GHz) and output power ( 27dBm). Three different technologies have been used (silicon BJT, CMOS and GaAs HBT) and several important parameters (output efficiency, power...

This paper presents the design of a neural network based feedback linearization (NNFBL) controller for a two degree-offreedom (DOF), quarter-car, servo-hydraulic vehicle suspension system. The main objective of the direct adaptive NNFBL controller is to improve the system’s ride comfort and handling quality. A feedforward, multi-layer perceptron (MLP) neural network (NN) model that is well suit...

Switched capacitor power amplifiers (SCPAs) are a class of digital transmitters which have shown promising results for high linearity with good DE. Their is limited by AM-PM distortion, caused difference in output conductance switching and non-switching driver cells. Often, DPD required to transmit higher order modulation schemes. In this letter, cell implementation as an inverter drain resisto...
