Adaptable Networked Control System for Lateral Control of Aircraft Models

摘要

This is an exploratory research which looks into a networked adaptive control design methodology for commercial aircrafts operating under uncertain flight conditions. The methodology is developed and used to design a networked adaptive control system. A generic transport model (GTM) of commercial aircrafts is used to extract a linearized model of its latitudinal dynamics and it was utilized for testing the effectiveness of the developed adaptive control system. In this work, an adaptive controller is developed using a linear quadratic regulator (LQR) method and is used as the base of the adaptive reference control system. A reference model is designed based on the linearized model of the aircraft to simplify the design process which guarantees the stability of the developed adaptive controller. The controller is then implemented in the form of networked control system. Finally, the two different implementations of the control system are tested using the aircraft linearized model. The results obtained from testing of the directly connected adaptive controller produced an acceptable performance under different operating flight conditions. Next, a comparison between the performance of directly connected adaptive control system and the networked control system is conducted with different network configurations between the sensors, controller, and reference model. Details of the design process and the test results of the developed adaptable reference control system and the networked control system are reported in this paper.
