A research on state identification and control method based on extended state observer

摘要

This paper focuses on the study of the transition control of hypersonic vehicles with two stages of flight. An active disturbance rejection controller with special instruction generation and double-loop extended state observers (ESO) is proposed, which realizes the identification and control of the equilibrium state. Both instruction and observers design method are present to ensure the accuracy as well as convergence. Simulation results show that this method is effective and feasible.
