考虑到控制用量的经济性,对直接力和尾舵复合控制的导弹设计俯仰平面模糊逻辑自动驾驶仪。依据专家经验,设计从误差信号到控制量的非线性映射,避免了稳态时同时作用的两个执行机构存在竞争的矛盾。文中给出了模糊逻辑控制器的设计方法,以及复合控制和气动舵单独作用时的仿真对比结果。结果表明所设计的模糊逻辑复合控制系统具有快速响应和节约燃料的优越性。

A pitch plane fuzzy logical autopilot was designed for a missile simultaneously controlled by aft tails and reaction jets when economic control usage was considered. The designed nonlinear mapping from the error signals to the control signals according to expert experience makes the conflict between the two competitive control mechanisms in steady state be avoided. The method of designing fuzzy logic controller applied to a dual controlled missile plant and the corresponding simulation results of dual control and aero-only control were presented. It is shown that the designed dual control system has great superiority in rapid response and fuel economization.
