On the Active Disturbance Rejection Control Based Guidance Law Design with Angle Constraint
Considering model uncertainties and pneumatic disturbances in the complex flight environment during the aircraft terminal guidance process,a guidance law with angle constraint is introduced based on the Active Disturbance Rejection Control (ADRC).The un-modeled dynamics,unknown acceleration information and unpredictable disturbances are lumped together and considered as the total disturbance in this paper,which is then estimated by Extended State Observer (ESO) and compensated in real time.The proposed strategy is independent of the model accuracy and predictive information of missile.The simulation results demonstrate that the scheme proposed under angle constraint is effective and the impact attitude angle is confined to a certain limit,leading to a higher guidance precision and strong robustness for the maneuvering target.
