Programming of PIC Micro-Controller for Power Factor Correction
First Asia International Conference on Modelling & Simulation (AMS'07), 2007In recent years, the power quality of the AC system has become a great concern due to the rapidly increased numbers of electronic equipment, power electronics and high voltage power system. In order to reduce harmonic contamination in power lines and improve transmission efficiency, power factor correction research became a hot topic.

Laser correction of geometric errors of multi-axis programmed-controlled systems
Measurement Techniques, 2012A method of laser correction of the geometric errors of multi-axis programmed control equipment, such as machine tools and plate measuring engines, as well as a traditional standardized method of correction of geometric errors with respect to individual coordinate axes and a method of correction of the total three-dimensional error are considered.

Timer error correction method for automatic regeneration of sequential control programs
1997 IEEE 6th International Conference on Emerging Technologies and Factory Automation Proceedings, EFTA '97, 2002It is difficult to replace or maintain many plants that were developed in the 1960s, because the original documents of installed sequential control logics are seldom still in existence. Therefore, our research group has proposed a sequential logics automatic regeneration method with an inductive learning algorithm which we have named SPAIR.

FEDC: Control Flow Error Detection and Correction for Embedded Systems without Program Interruption
2008 Third International Conference on Availability, Reliability and Security, 2008This paper proposes a new technique called CFEDC to detect and correct control flow errors (CFEs) without program interruption. The proposed technique is based on the modification of application software and minor changes in the underlying hardware. To demonstrate the effectiveness of CFEDC, it has been implemented on an OpenRISC 1200 as a case study ...

The residual method which is one of the standard regularization procedures for ill-posed optimization problems is applied to an improper convex programming problem. A typical problem for the residual method is reduced to the minimization problem for the quadratic penalty function. For this approach, we establish convergence conditions and estimates for

Self-Correction and Dead-Beat Current Control Strategy for Digital Programmed Boost Converter
2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019Boost converters are widely used for photovoltaic power generation, energy storage and electric vehicles. Dead-beat current control strategy, one of the most attractive digital current control strategies, enables the inductor current to reach the current reference in a minimal finite number of sampling cycles among digital current control strategies ...
