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).

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 ...

A self-tuning automatic voltage regulator
Electric Power Systems Research, 1979Abstract A self-tuning automatic voltage regulator (AVR) for a synchronous generator is presented. The regulator proposed improves the system stability; it is simple and can handle stochastic load changes. The algorithm for the proposed AVR combines a least-squares estimator with a minimum variance control strategy computed from an estimated model ...

Turbogenerator self-tuning automatic voltage regulator
IEEE Transactions on Energy Conversion, 1999Results are presented from new self-tuning controllers for turbogenerators. Simulations and micromachine tests have been successful, with a prototype self-tuning controller being manufactured. This is intended as a direct replacement for a conventional AVR, so a more conventional fixed parameter controller is also considered, serving as a comparison of

Automatic voltage regulator with fastdynamic speed
IEE Proceedings - Electric Power Applications, 1999A 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 ...
