Title Roll Channel Controller Design of Airborne
Time-critical Guided Bomb
Abstract
During the flight of airborne time-critical guided bomb after being separated from the aircraft, parameters of pitch, yaw and roll channel would be coupled usually, so the control system is usually designed independently for each channel followed by a decoupled channel. Based on classical controller system theory, this paper designed the controller system for roll channel of the airborne time-critical guided bomb, and the function of this system is tested and verified in time and frequency domain. Based on that, the six-degree ballistic simulation is conducted and simulation results have proved that the designed control system is reasonable and can meet the requirements of the whole system.
In addition, as aerodynamic parameters change widely when the guided bomb is flying in large and nonlinear space with the change of height and Ma. So the accuracy can be affected during the whole flight trajectory when using traditional controller. Therefore, at the end of this paper, a method of gain scheduling controller designing method is proposed, which can then effectively improve the accuracy and provide a theoretical basis for further controller optimization.
