Aiming at the modeling and unmodeling uncertainty of the photoelectric stabilized platforman Adaptive Robust Control (ARC) algorithm based on disturbance estimation is proposed.The algorithm combines ARC with the Disturbance Observer (DOB)and integrates the disturbance estimation results obtained by DOB into the design of ARC algorithm.The adaptive control law of ARC is used for adaptive compensationso as to further improve the stabilized accuracy of the photoelectric stabilized platform.The simulation results show that:Compared with the traditional DOB feedforward compensationthe proposed algorithm has the advantages of smaller overshoot and shorter adjustment timewhich effectively improves the disturbance suppression ability of the photoelectric stabilized platform.
