“…From the potential application perspective, the proposed method has a strong universality. After considering the mechanical characteristics of many AECS, including cabin temperature control system [39], hydraulic control system [40], and landing gear steering control system [41], three common characteristics between them can be described as follows: (1) ensuring flight safety and quality; (2) SISO; (3) existing some potential faults. erefore, the proposed method has the possibility to be applied to other AECS.…”

The Cabin Pressure Control System (CPCS) is an essential part of the aviation environmental control system that ensures aircraft structure and flight crew safety. However, the CPCS usually has potential faults of sensors and actuators. To this end, a Simple Adaptive Control- (SAC-) based reconfiguration method is proposed to compensate for the above adverse effects. Some good pressure control performance of CPCS can be achieved by the basic pressure controller when the system is in normal operation. A parallel feedforward compensator is designed to guarantee the closed-loop system’s stability and the almost strictly positive realness of the augmented system. Thus, the simple adaptive controller can be utilized for the CPCS. In particular, the reconfiguration system can update the control law online when the fault occurs without the system identification process. The reference model is obtained by mathematical model linearization after considering the mechanical characteristics of the CPCS. Extensive simulations under various typical fault scenarios are carried out throughout the entire flight envelope of the aircraft from take-off to landing. Simulation results validate the robustness and reconfiguration control capability of the proposed method.

In order to automate the ground maneuvering of a civil regional aircraft and improve the efficiency of the air transport system, a fly-by-wire nose wheel steering system (NWSS) was designed. A rack and pinion steering mechanism integrated with a single actuator mechanism was proposed. The basic control circuit diagram with integrated test, the electro-hydraulic system diagram, and the mathematical model of the steering system were established and analyzed. A co-simulation model of the system was built to verify the control law. The results show that the properties of the prototype meet the design requirements. Given the importance of the NWSS, the simulation results can be used to optimize the basic design parameters. This methodology can also be used for other types of aircraft.
