Today’s on-board low-voltage, high-current dc-dc voltage regulator module (VRM) requirements for the new generation of IC’s and microprocessors are increasingly becoming stricter than ever as the demand for high dynamic performance and high power density converters continues to increase. A new scheme that combines interleaved technique and voltage-mode hysteretic control approach, by upgrading ...

The objective of this paper is to present the methods of development and study of control law of rodless pneumatic actuator with fuzzy regulator in order to improve the accuracy of the pneumatic drive carriage positioning. The basis for improving the accuracy of positioning of the pneumatic actuator is the Intelligent Control System.

voltage control is one of the imperative issues in the smart distribution control system. while traditional distribution network is equipped with communication and monitoring equipment, the online voltage control can be perfectly achieved. with using these smart grid technologies, the distribution voltage control schemes should carry out intelligently and cover the undesirable effect of high pe...

This paper presents a DSP-based high performance digital automatic voltage regulator (D-AVR) for use on engine generator. The H∞ control approach is applied to the engine generator excitation control system (ECS) for the purpose of tracking a r.m.s. of sinusoidal ac voltage to a specified value. Since the implementation of the control laws has tended to the digital microprocessor, the paper ext...

Renewable energy sources like wind, sun, and hydro are considered as a reliable alternative to the traditional energy sources such as oil, natural gas, or coal. This paper describes modeling and simulations to determine a method for the power performance evaluation of autonomous wind turbine system. A speed control regulator is utilized to control the DC bus voltage. The inverter gate’s signals...

This paper proposes a fully digital control of boost Power Factor Preregulators (PFPs) with input voltage estimation. The proposed solution is based on a conventional multi-loop structure for PFP with an internal current control and an outer voltage control possibly with fast dynamic response. Instead, input voltage sensing is avoided by using a conventional PI (proportional-integral) current r...
