摘要
针对穿浪双体船高速情况下的纵摇和垂荡运动影响乘船舒适性的问题,分析了穿浪双体船的运动规律,给出了其纵向运动控制模型,并根据控制模型的多输入多输出系统特点,分别针对纵摇和升沉两个通道设计了独立的PID控制器。在此基础上,进一步将模糊控制理论应用于PID参数的整定,给出了具体的设计方法,并根据人工经验设计了详细的参数整定规则。经仿真分析表明:模糊逻辑的引入使得PID控制器具备了自适应功能,能够取得更好的减摇效果。
To weaken the influence of a severe pitching and heave caused by the wave-piercing catamaran moving at high speed on passengers′comfortability,this paper discusses the longitudinal-motion fuzzy PID control design for the fin stabilizer,analyzes the motion characteristics of the wave-piercing catamaran and offers its mathematic mode for longitudinal motion control.According to a MIMO system,two independent PID controllers,one for pitching motion and the other for heaving motion,are designed respectively.On this basis,the fuzzy control theory is further applied to the adjustment of PID control parameters.For the roll stabilization effect,the fuzzy PID control is better than the conventional PID control.And the paper proposes the concrete design method and detailed rules set for PID parameters.Simulation results show that the proposed method is effective.
