| 摘 要： | 飞行器空速／高度的精确解耦跟踪，控制本质上是非最小相位输出精确解耦跟踪控制问题，由于存在内动态不稳定性，经典逆系统方法无法使用。将稳定逆办法与滑模控制相结合来解决存在的问题。首先针对稳定逆非因果性带来的问题，给出了一种稳定逆因果近似解的求法，经计算证明了近似结果误差的渐近收敛特性；然后利用稳定逆困果近似解将输出跟踪问题转化为不确定系统的鲁棒镇定问题，并对滑模控制和干扰观测器设计了相应的反馈镇定控制器。经过仿真表明综合稳定逆因果近似解和滑模控制的方案既发挥了逆系统方法的动态解耦能力，又利用了滑模控制的鲁棒性实现飞行器空速／高度精确解耦跟踪控制，也可以很好的兼顾控制器的鲁棒性和抗干扰性。

| Abstract: | Precise decoupling tracking of airspeed and altitude for conventional takeoff and landing aerial vehicles is essentially a nonminimum-phase output tracking problem.Stable inversion and sliding mode control are adopted to solve this problem.Firstly,a method for calculating the causal solution of stable inversion is proposed.The merit is that it doesn't need the output trajectory to be a given time parameterized function.Then the output tracking problem is transformed into a state tracking problem which is fi... |
