英文摘要	In this paper, a control strategy with a model-assisted linear extended state observer (MLESO) is proposed to enhance the disturbance suppression performance for OptoElectronic stabilized platform. First, we incorporate known model information which can be identified from the open loop frequency response of controlled plant in the framework of the presented linear extended state observer (LESO), for the degree and high order gain of the controlled plant are enough. The tuning parameters of observer gain and controller gain are reduced to two: observer bandwidth and controller bandwidth. Then, constructing a MLESO can estimate and compensate the generalized disturbance to stabilize line of sight (LOS). Simulation results indicate that system with MLESO shows a stronger disturbance rejection ability in low and medium frequency by a simple linear PD control law, compared with traditional single position closed-loop control system. © 2019 IEEE
