摘要
针对大气层内飞行的质量矩导弹,提出了一种基于模糊逻辑的姿态控制规律。在建立了3轴稳定质量矩导弹姿态运动模型的基础上,制定了3个方向上滑块位置对应的模糊规则表,并通过分析角加速度和遍历条件的关系对3个滑块位置协调控制。同时利用遗传算法根据指定的性能指标对PD控制参数进行离线校正。仿真结果表明,该方法能在保证系统稳定的情况下有效实现导弹的姿态调整。
An attitude control law based on fuzzy logic is presented for the mass moment missile in intraatmospheric space. After constructing the model of the attitude movement with three-axis stabilization, the fuzzy regular tables corresponding with the moving mass position in respective axis are constituted. According to analysis of the relation between angular acceleration and searching condition, three moving mass positions are regulated in phase. Simultaneously the PD control parameters are offline revised using genetic algorithm according to the specific performance index. Simulation results show that the system stabilization can be satisfied to realize efficiently attitude adjustment for missile.
