4.1.15.1 LQR (linear quadratic regulator)

LQR (linear quadratic regulator) is an advanced mathematical control algorithm used to optimize the dynamic behavior of complex systems, such as flight control or fuel metering networks, by minimizing state errors. This method is highly effective for maintaining optimal aircraft balance and fuel efficiency under turbulent atmospheric conditions. Challenges in developing these controllers lie in the high mathematical complexity of proving stability across highly non-linear, unpredictable flight regimes.
