摘要
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。
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/Simulink. Comparison with pseudo - inverse method and the system simulation results show that the fixed - point method can not only achieve the desired objective accurately, but also distribute multi - control - effectors efficiently and the control effectors are ensured in position constrains. So the feasibility and effectiveness of this method are validated.
