【Abstract】 The design methods for guidance control systems are overviewed from the aspects of modeling and control. Key problems of high system order and high uncertainties are discussed. For a 3-D system, we propose an integrated guidance and control approach with active disturbance rejection control(ADRC). The controller is featured with simple structure and with online estimation and compensation for the nonlinear time-varying uncertainties in the flight control system. Simulation results show the effectiveness of the proposed approach for dealing with large uncertainties in the integrated system.更多还原
