Abstract
This paper discusses the development of a Linear Quadratic Regulator (LQR) control for switching converters with non-minimum phase characteristics. It introduces a feedback loop with a Kalman filter to address observability issues in high-gain converters and simplify control processes. The paper examines design challenges and demonstrates the improved system performance through MATLAB/Simulink simulations.
