中文摘要：

针对以舰船为射击平台的舰载火箭炮，由于海上风、浪、流等多种因素的作用，射击线受到舰船摇摆而影响射击精度的问题，应用模糊控制理论和灰色预测理论，设计了一种基于预测步长自调整的灰色预测模糊控制器，通过对实时状态的模糊判决，实现对灰预测步长的自适应调整，从而改善控制效果。陆上及海上实验表明，系统达到了规定的动静态技术指标。

英文摘要：

Based on the platform of ship,the shipbased rocket launcher falls under the integrated effects of wind,wave and stream,the stability of firing accuracy was influenced by the ship swing.A grey predictive-fuzzy integrated controller with self adjusting step was designed based on fuzzy control theory and grey prediction theory.By the fuzzy judgment of current state,the controller can adaptively adjust the grey predictive step,and hence improve the control effect.The simulation and experimental results show that compared with separate control or without control,the integrated control scheme proposed can improve the dynamic performance more effectively and eliminate the stable error.
