Abstract

The attitude control systems play an extremely important role in flight control systems. In order to ensure the safety and stability of flight control system, it is necessary to evaluate the performance of attitude control system effectively. In this paper, a data-based performance evaluation method for aircraft attitude control system performance is proposed. The structure of the aircraft attitude control system is analyzed, a hierarchical performance evaluation indicator system is established, and the calculation method for each lowest indicator is given. Considering the equilibrium of the system in the evaluation, a variable weight determination method is proposed. A supporting evaluation tool is developed, through which an example of aircraft attitude control system performance evaluation is given and the result of the evaluation example is analyzed which is benefit to the study of the performance evaluation of aircraft attitude control systems.
