title = "Disturbance Suppression of Seeker Servo System Based on Fuzzy ESO and Sliding Mode Control",
abstract = "A compound controller based on the fuzzy Extended State Observer(ESO) and sliding mode control (SMC) is designed to address the problem of numerous disturbances in the seeker servo systems. Disturbances such as external disturbance torques and parameters perturbation can be estimated by ESO and then suppressed effectively by SMC. At the same time, considering that the seeker servo system often operates in a time-varying state, a fuzzy control is designed based on the frequency of disturbances to adaptively adjust the ESO parameters. The results of simulation show that compared with the sliding mode control with fixed parameter ESO, the designed fuzzy ESO has a better estimation effect on time-varying disturbances. Besides, the designed compound controller can effectively improve the positioning accuracy and speed stability of the seeker servo system under external multi-source disturbances.",
