Abstract
A dynamic model of the optical glide path axis stabilization system is presented. An algorithm for estimating the parameters of the system state vector based on an observer in the form of a Kalman filter and a control algorithm using a linear-quadratic regulator are constructed. The system is synthesized with nominal model parameters and perturbation characteristics that depend non-linearly on the state vector. It is shown that the stabilization error under these conditions is ±46". The sensitivity analysis of the constructed algorithm is carried out to account for the possible deviation of the model parameter values from the nominal values.
