The photovoltaic powered water pumping system investigated in this paper consists mainly of a photovoltaic generator, a boost converter, a three phase inverter, and an induction motor-pump. Then, we present a method which resolved directly on the bond graph the problem of input/output linearization of the nonlinear system while basing itself on input/output causal inversion of its BG model. Ana...

A bond graph model of a two degrees of freedom PUMA is described. System inversion gives the system input required to generate a given system output. In order to get the system inversion of the PUMA manipulator, a linearization of the nonlinear bond graph is obtained. Hence, the bicausality of the linearized bond graph of the PUMA manipulator is applied. Thus, the bicausal bond graph provides a...

In this paper, we study the regulation problem for the ball and beam system. Since the system does not have well deened relative degree, exact input-output lin-earization method may fail. The approximate lineariza-tion approach can only be used in a limited region. By representing the system as a fuzzy dynamic model, we give a global control law which is the weighted average of two local stabil...

This paper presents a new efficient approach for performing linearization of Simulink R © models. It improves the efficiency of existing linearization algorithms using a Jacobian graph, a graph-based data structure that captures the linear relationship between input, output and state variables. The graphbased algorithm enables the use of graph transformations to reduce the size of the Jacobian ...

New linearization technique that reduces the thirdand fifth-order intermodulation products is proposed in this paper. It suggests the injection of second harmonics (IM2) at the amplifier input whereas the IM2 signals and fourth-order nonlinear signals (IM2+IM4) are fed into the amplifier output. The reduction of the thirdand fifth-order intermodulation products has been achieved by applying a n...

Multi-motor synchronous system is a multi-input multi-output, nonlinear and high coupling control system. The neural network generalized inverse system can realize the linearization and decoupling of the nonlinear control. Local minima, irrationality learning rate and over learning easily occur in traditional feedforward neural networks. To overcome the problems, it put forward a single hidden-...

Constructive coordinate transformation problem of nonlinear systems into a particular state-affine systems and the analysis of their equivalence, is here tackled. The proposed method is based on the analysis of the Input/Output Differential Equation structure of these nonlinear systems. The polynomial structure of their corresponding state-affine system is then explicitly given and new necessar...
