  • Test rocket has been an attractive platform for scientific and educational experiments during the last several years. Aiming at providing a potential engineering application of disturbance rejection control to aircraft control system design following traditional frequency-domain methods, this paper presents an enhanced disturbance rejection control of two degrees of freedom based on H¿ synthesis and equivalent-input-disturbance (EID) for 3-axis attitude controller design of a small solid test rocket. The establishment of an EID system regards the mismatched disturbance as a `total disturbance¿ in the input channel for compensation. The H¿ synthesis based on classical frequency-domain analysis is applied to the design of a disturbance filter and of a composite feedback controller. In terms of the controller design, the system including the filter is considered as a whole to guarantee the stability of the overall system without separate design. Furthermore, the proposed method is successfully applied to the 3-axis attitude controller design of the test rocket by modeling the nonlinear dynamics as linear EID formulations of attitudes. The simulation and validation including Monte-Carlo bias simulation and comparison with active disturbance rejection control (ADRC) based design, Hardware-in-the-Loop (HIL) simulation and flight test are conducted specifically. The results verify the effectiveness of the proposed method with excellent performance and practical prospects. © 2018 ISA
