A Mixed LQRI / PI based Control for Three-Phase UPQCs
Leonardo M. Landaeta Cristian A. Sepúlveda José R. Espinoza Carlos R. Baier
abstract.- A mixed Linear Quadratic Regulator with an Integral action control technique applied to a Unified Power Quality Conditioner (UPQC) is presented. The UPQC is based on a back-to-back connected series and parallel compensators sharing a common DC link. The proposed control approach becomes a robust control scheme that is able to keep regulation and stability even under extreme parameter and load power factor variations. The design of the controller parameters uses the well known Riccati equation based on the discrete approximation of the linearized model of the UPQC. Key waveforms based on simulated extensive work shows the feasibility of the proposed approach.

Abstract.- Power Quality disturbances has been faced through so called Custom Power Devices such as
Static Series Compensator (SSC) and Distribution STATic COMpensator (DSTATCOM) which
provide part of the compensation capabilities required. To provide total functionality it
is possible to jointly operate both equipments or to use a Unified Power Quality
Conditioner (UPQC) which integrate both topologies providing full compensation
capabilities and moreover improving compensation characteristics. How to best utilize
this advantages and inspects the reasons behind them are the mains topics of this work.
