Desenvolvimento de um controlador baseado em realimentação de estados utilizando estimadores de ordem reduzida para geração distribuída

This paper presents a distributed generation system using power static converter connected to mains through an LCL filter. The control law is based on state feedback. modelled in synchronous reference allowing the use of integral actions for eliminating state-steady errors active and reactive powers DC voltage controls. feedback gains are calculated Linear Quadratic Regulator methodology starting from Bryson’s rule procedure tune shown dynamic response system. Besides that, reduced-order observer included reduce required number sensors output Simulation results presented verify estimated states this work.
