A novel two step adaptive identification framework is proposed for sinusoidal signals to
estimate the unknown offset, amplitude, frequency and phase, where only the output …

Voltage source inverters (VSIs), especially uninterrupted power supply for critical loads,
require high steady-state performance, fast transient response, and strong robustness …

Repetitive control (RC) is found to be a high-performance control scheme for constant-
voltage constant-frequency (CVCF) pulsewidth-modulated (PWM) converters to eliminate …

In this paper, a repetitive-based controller for the compensation of 6 lscr plusmn 1 harmonic
components is proposed. This control scheme is more appropriate for processes that involve …

This paper presents the design and implementation of a linear quadratic regulator (LQR)
with integral action (LQRI) for a three-phase three-wire shunt active filter (SAF). The integral …

Tracking and rejecting periodic signals are common tasks in many control applications. A
well-known use of Repetitive Control (RC) is to both track a periodic reference signal and …

This paper proposes a down-sampled discrete-time internal-model-based controller in the
synchronous reference frame with a reduced number of poles. This controller is suitable for …
