Abstract

In this work, the design of a linear quadratic regulator with a Kalman filter is presented using the loop transfer recovery method (LQG-LTR) for DC-AC converters with an LCL filter. The main objective is to mitigate the noise in the control effort caused by the high-frequency components in the converter currents. To achieve this, only the voltage across the capacitors is feedback and the currents are estimated. The results of this method were compared with a known LQI controller. The results show that the LQG-LTR controller mitigates the noise in control effort and minimizes tracking error.
