Technological Strategy of Using Global Positioning System: An Analysis

The Global Positioning System (GPS) is a U.S. space-based radionavigation system that provides reliable positioning, navigation, and timing services to civilian users on a continuous worldwide basis -freely available to all. GPS provides specially coded satellite signals that can be processed in a GPS receiver, enabling the receiver to compute position, velocity and time. Basically GPS works by...

A Redefined Discrete Quasi - Sliding Mode Strategy

Variable structures with sliding mode control (SCM) are one of the best techniques for analyzing the dynamics of nonlinear systems, not only in continuous domain but also in discrete domain. This paper presents a redefined discrete quasi-sliding mode control strategy. The reaching law condition defined in the presently available technique is redefined in this paper. For systems with both time i...

Neuro-Sliding Mode Control of Piezo-Positioning Mechanism

In this work, a Neuro-Sliding mode controller (NSMC) for piezo-positioning mechanism (PEA) was designed. This controller takes into account parameter uncertainties and unknown external disturbances. The LuGre model is used to establish the mathematical model of the system including the mechanical motion dynamics, the hysteresis friction, the load disturbance and parameter uncertainties. Using t...
