Modelling of dynamic modes in a DC motor for electric vehicle

Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska
The paper investigates mathematical models of a DC electric motor with independent excitation for electric vehicles and PWM as a speed control method. Differential equations of electromechanical state are written in normal Cauchy form.

Mathematical Programming Method Based on Chaos Anti-Control for the Solution of Forward Displacement of Parallel Robot Mechanisms

International Journal of Advanced Robotic Systems, 2013
The pose of the moving platform in parallel robots is possible thanks to the strong coupling, but it consequently is very difficult to obtain its forward displacement.

Compromise optimum allocation in neutrosophic multi-character survey under stratified random sampling using neutrosophic fuzzy programming

Heliyon
Survey sampling has wide range of applications in social and scientific investigation to draw inference about the unknown parameter of interest. In complex surveys, the sample information about the study variable cannot be expressed by a precise number ...

Contributions to numerical methods for complementarity problems and mathematical programs with complementary constraints

, 2017
In this thesis, we studied the regularization methods for the numerical resolution of problems with equilibria. In the first part, we focused on the complementarity problems through two applications that are the absolute value equation and the sparse optimization problem. In the second part, we concentrated on optimization problems with complementarity

OPTIMAL SYNTHESIS OF A MANIPULATOR USING TWO COMPETITIVE METHODS

Facta Universitatis. Series: Mechanical Engineering, 2014
This paper defines a program realization for finding the optimal geometry of a planar Z-mechanism. The paper shows the mathematical procedure for defining the objective function, the constraint function and the search fields which are used for solving ...
