On flight control implementation, the control surface actuator system plays one of the key roles that will significantly affect the closed-loop performance of the aircraft. The actuators must provide the required effort for moving the control surface so that the desired control action can be reached. Any failure on the actuator system will limit or degrade the operation of the control surface, so that it will affect the performance of the system in controlling the aircraft, or even worse, may bring the aircraft into an unsafe condition. In this project, the effect of some control surface problems due to actuator failures are modeled, simulated, and analyzed. To reconstruct the situation, the control device failure model is integrated into the flight dynamic model of an aircraft. The numerical model of the equation then is used for simulating the aircraft response under some failure conditions. It can be seen from the simulation results that control surface failure can significantly affect the trim condition of the aircraft, since the failures can change the balance of forces and moments that work on the aircraft. The simulation results also show that for some control surface failures may initiate an asymmetrical response from the aircraft dynamics. On closed-loop simulations, where some type of flight control systems for stabilization and maneuvering tasks are implemented, control surface failures may affect the performance of the control system. The results of the study suggest that any possibilities of control surface failure must be anticipated, by using a robust control scheme or other reconfigurable schemes that can cope with the change in the dynamic characteristics due to the failures.

在飞行控制实施中，操纵面执行器系统起着关键作用之一，将显着影响飞机的闭环性能。执行器必须提供移动控制面所需的力，以便达到所需的控制动作。执行器系统的任何故障都会限制或降低操纵面的操作，从而影响系统控制飞行器的性能，甚至可能使飞行器进入不安全状态。在该项目中，对由于执行器故障导致的一些控制面问题的影响进行了建模、模拟和分析。为了重建情况，将控制设备故障模型集成到飞机的飞行动力学模型中。该方程的数值模型然后用于模拟飞机在某些故障条件下的响应。从仿真结果可以看出，操纵面失效会显着影响飞机的配平状况，因为失效会改变作用在飞机上的力和力矩的平衡。仿真结果还表明，对于某些操纵面故障可能会引发飞机动力学的不对称响应。在闭环仿真中，执行某些类型的用于稳定和机动任务的飞行控制系统，控制面故障可能会影响控制系统的性能。研究结果表明，必须预测任何可能的操纵面故障，
