Simulation Results

In order to realize accurate flight control system design and simulation, an integrated scheme of aircraft model which consists of flight dynamics, fly-by-wire (FBW) platform and flight environment is proposed. Flight environment includes gravity, wind, and atmosphere. And the actuator and sensors such as gyroscope and accelerometer models are considered in the FBW platform. All parts of the integrated model are closely connected and interacted with each other. Simulation results confirm the effectiveness of the integrated aircraft model and also indicate that the (Flight Control Law) FCL must be designed with robustness to sensor noise and time delays with the FBW platform in addition to the required robustness to model uncertainty in flight dynamics.

Simulation Results

This paper describes the design of centralized controller for two variable processes. The two variable process structures are somehow different from the single variable processes. This difference is occurred because of interrelations between the variables present in the process. Hence, when a controller is planned for such systems, the relations amid the variables must be taken into consideration. This process is done in decentralized control system design. But decentralized control system works well when the interrelations between the variables are simple. If the interaction is strong, then the centralized control system is preferred since it uses a controller for each pair of input and output variables. The controller used in main diagonal works for improving the servo performance and off diagonal controller reduces the interrelation effect. So the performance is improved by minimizing the interrelation effects. The design process is easy to understand by field engineers working in industries. The simulation results are included in this paper to specify the efficacy of the proposed scheme.

Saturation Phase

The former research on the overload control system of a supersonic missile didn’t consider actuator saturation. In order to reduce the windup effect caused by actuator saturation, we developed a dynamic anti-windup compensator. The overload control system design adopted a two-step approach. Firstly a sliding mode controller was designed ignoring the saturation. Secondly a dynamic anti-windup compensator was designed. It added to the control system to reduce the windup effect. It disengaged the actuator fast from saturation phase after the actuator entered saturation. Simulation results showed that the dynamic anti-windup compensator reduced 52% of saturation time of the control system. Hence the performance of the overload control system is improved effectively.
