不动点法在飞控系统控制分配中的应用

针对多操纵面战斗机飞行控制系统中的控制分配问题,提出了一种不动点法控制分配策略。方法在伪逆法的分配基础上,采用不动点迭代法进行优化求解,既利用了伪逆法实时性好,易于实现的优点,又解决了伪逆法无饱和约束限制的缺点,并且使可行解的范围扩大到了整个可达集。在Matlab/Simulink中建立控制分配系统的数字仿真模型,并进行计算机仿真,结果表明,策略不仅能得到期望的三轴力矩,而且能很好地分配各个操纵面,使其均工作在约束范围内。结果验证了不动点法的可行性和有效性。

Application of Fixed-point Method in Control Allocation of Flight Control System

Control allocation method was investigated for the problem of flight with multi-control-effectors. In this paper,an optimal control allocation method,fixed-point method (FXP),was proposed. This method was based on pseudo-inverse method,it took the advantages of good real-time performance and easy implementation of pseudo-inverse method and solved the problem of actuator saturable constraints,and the feasible and optimal solution was extended to the entire set. The simulation model was built in Matlab/Simuli...
