随着飞行器控制技术的发展,直接力、推力矢量等控制执行技术在飞行器控制领域得到广泛应用。直接力与推力矢量都具有对飞行器姿态控制效率高、精度好等优点,但推力矢量对姿态控制的响应速度不如直接力响应快,而直接力长时间开启会消耗大量燃料。结合直接力与推力矢量的控制特点,设计了直接力与推力矢量复合控制策略。以某飞行器为研究对象,建立了飞行器的动力学与运动学模型以及直接力与推力矢量模型,提出了直接力/矢量推力复合控制技术的分配策略。经仿真验证表明,复合控制方法及控制分配策略使控制系统具有较快的响应速度和控制精度。
With the development of aircraft control technology, the control and execution technologies such as direct force and thrust vector are widely used in the field of aircraft control. Both direct force and thrust vector have the advantages of high efficiency and good accuracy for attitude control of aircraft. However, the response speed of thrust vector to attitude control is not as fast as direct force response, while the direct force and long time opening will consume a large amount of fuel. Combined with the control characteristics of direct force and thrust vector, the composite control strategy of direct force and thrust vector is designed. Taking an aircraft as the research object, the dynamics and kinematics models and the direct force and thrust vector models of the aircraft are established, and the allocation strategy of the direct force / vector thrust compound control technology is put forward. The simulation results show that the composite control method and the control allocation strategy make the control system have faster response speed and control accuracy.
