摘　　要：根据零航速下减摇鳍的运动方式,对减摇鳍在非定常流中的受力情况进行分析,建立了零航速减摇鳍的升力模型。利用CFD软件Fluent对零航速下减摇鳍升力进行数值仿真,依据仿真数据通过回归分析方法整定升力模型待定参数。针对升力模型的非线性特性和系统模型的不确定性,设计了基于PSD算法的单神经元控制器。仿真结果表明按该种思想设计的零航速减摇鳍系统取得了满意的减摇效果,且控制器对系统非线性和不确定性具有较好的自适应能力。The forces on fin stabilizer were analyzed in non-steady flow based on the special working of zero speed fin stabilizer. The lift on zero-speed fin stabilizer was simulated with Fluent. The lift model was set up and it was modified with the data from simulation. For the non-linear lift model and uncertainty of the system, a Neuron PID controller was designed based on PSD algorithm. Simulation shows that this anti-roll system has a good exhibition and the controller has a strong adaptability for the uncertain system.
