FOPID controller with fractional filter for an automatic voltage regulator
Computers and Electrical Engineering, 2021Abstract This article presents a novel fractional order proportional–integral–derivative (FOPID) controller with fractional filter for an automatic voltage regulator (AVR) system. The proposed controller has seven independent parameters to be set.

Automatic voltage regulator with fastdynamic speed
IEE Proceedings - Electric Power Applications, 1999 A novel automatic voltage regulator is proposed and analysed. The power circuit is made up of a pulse-width modulated (PWM) buck-boost AC chopper which uses only two standard switch modules. In the AC chopper, the commutation scheme allows dead-time to avoid current spikes from switching and at the same time establishes a current path in the inductor ...

Three-Arm AC Automatic Voltage Regulator
IEEE Transactions on Industrial Electronics, 2011In this paper, a novel ac automatic voltage regulator (AVR) is proposed. This AVR is configured by an input inductor, an output filter, a small-capacitance dc capacitor, and a three-arm power converter. This three-arm power converter acts as an ac boost converter when the utility voltage is lower than the specified voltage.

Robust Controller Design for Automatic Voltage Regulation
2020 American Control Conference (ACC), 2020In this paper, a robust controller is developed for an automatic voltage regulator (AVR) in power systems. In reality, the voltage at each substation fluctuates constantly due to disturbances. These voltage disturbances are mainly caused by load changes and loss of equipment.

MATHEMATICAL MODELLING OF AN AUTOMATIC VOLTAGE REGULATOR
Journal of Circuits, Systems and Computers, 1996This letter describes the mathematical modelling of an automatic voltage regulator (avr) in a form which is compatible with models developed for many other items of electrical plant. The corresponding equations are suitable for numerical solution on a digital computer, and results are presented to illustrate the performance when the avr program is ...

Optimal design of robust resilient automatic voltage regulators
ISA Transactions, 2021Uncertainties in the plant model parameters and perturbations in the controller gains imposed by implementation errors represent a challenge to ensure robust stability and controller non-fragility simultaneously. Optimal design of robust non-fragile proportional-integral-derivative (PID) controller is presented for an automatic voltage regulator (AVR).

Optimizing intensive automatic voltage regulator parameters
2009 5th International Symposium on Applied Computational Intelligence and Informatics, 2009The present paper focuses on the use of intensive automatic voltage regulators (AVRs) to improve the dynamic behaviour of high power synchronous generators (SGs) considering the influence of the entire power system (PS). The case study discusses the SGs within two significant power plants in Romania (Turceni and Rovinari).

Automatic voltage regulator using an AC voltage-voltage converter
IEEE Transactions on Industry Applications, 2000Voltage sags and extended undervoltages are one of the main concerns of industry today. These voltage sags could cause high negative impact on productivity, which is certainly an undesirable aspect in industrial and commercial applications. Current tap-changing transformers used in distribution systems have proven to be inadequate in solving these ...
