This work investigates the Feasible Direction Algorithm using interior points applied to the Mixed Nonlinear Complementarity Problem and some applications. This algorithm is based in Feasible Directions Algorithm for Nonlinear Complementarity Problem, which is described briefly. The proposed algorithm is important because many mathematical models can be written as mixed nonlinear complementarity problem. The principal idea of this algorithm is to generate, at each iteration, a sequence of feasible directions with respect to the region, defined by the inequality conditions, which are also monotonic descent directions for one potential function. Then, an approximate line search along this direction is performed in order to define the next iteration. Global and asymptotic convergence properties for the algorithm are proved. In order to validade the robustness the algorithm is tested on seve...

This paper with the problem of parameter identification and trajectory tracking of a nonlinear electro-mechanical system, which consists of a DC motor that drives a nonlinear load that resembles a one-degree-of-freedom robotic manipulator. The system presents two types of nonlinearity; one of a discontinuous nature, due to static and Coulomb frictions, and the other continuous, due to non-linear loading. Only the angular position of the nonlinear load is available for feedback purposes. Static and Coulomb frictions are modeled and compensated using a nonlinear compensation scheme that depends on the speed of the load. The unknown parameters of the nonlinear compensating and unloaded system are identified open loop in the frequency domain using Feedback Linearization. Finally, the implementation of the designed control system is presented, together with its experimental results, which are...

We consider a mixed problem for a system of nonlinear viscoelastic wave equations with p-Laplacian operator. Under certain conditions on the relaxation functions and the source terms, using the indirect method, we prove a result of global nonexistence for certain solutions with nonpositive initial energy as well as with positive initial energy.

In this work we are concerned with the existence of strong solutions andexponential decay of the total energy for the initial boundary value problem associatedwith the quasilinear wave equation with nonlinear source, under the assumption thatthe velocity boundary feedback is dissipative. The results are proved by means ofthe potential well method, the multiplier technique and suitable unique continuationtheorem for the wave equation with variable coefficients.
