The objective of this paper is to design an [Formula: see text] controller for an inverted pendulum system, synthesized using the [Formula: see text] loop shaping technique. In the [Formula: see text] loop shaping technique, a linear plant model is augmented with certain weight functions, such as the sensitivity weight function and complementary sensitivity weight function, so that the closed loop transfer function of the plant will have the desired performance. In this work, the [Formula: see text] controller is synthesized and the analysis on robustness and performance of the system is done by taking the singular value response and robustness indicator plots.

“…Similarly, Jee and Yalagach et.al. have addressed H-infinity control strategy [28] to design flight control system under the highly uncertainties and changing dynamics of aerodynamic coefficients for the RLV during reentry process. However, robust control scheme cannot achieve a good tracking performance easily since the robust controller is designed in the worst case of the control system.…”

In this paper, the attitude control problem of reusable launch vehicles (RLVs) during reentry phase is investigated by using compound adaptive fuzzy H-infinity control (CAFHC) strategy in the presence of parameter uncertainties and external disturbances. Firstly, the control-oriented attitude model is established by a model transformation based on the six-degree-of-freedom(6-DoF) dynamic model of the RLV. Secondly, a novel attitude control scheme is developed and the control strategy consists of two parts to achieve a stable and accurate attitude tracking during reentry flight process. An attitude tracking controller is designed utilizing adaptive fuzzy H-infinity control approach combined with an identification model to improve the attitude tracking performance in the interior of fuzzy approximation region of attitude angle. Next, an attitude stabilization controller based on boundary adaptive technique is employed to assure the robustness of the closed-loop system in the exterior of fuzzy approximation region of attitude angle. Furthermore, the stability of the closed-loop system is guaranteed within the framework of Lyapunov theory and the attitude tracking error converges to a small neighborhood around origin. Finally, the simulation results are presented to demonstrate that the effectiveness of the proposed control scheme for reentry RLV, and its tracking performance performs better than the other control method.
