摘要
鱼雷在大机动时滚动通道会出现严重的动力学耦合,为了减小耦合对滚动的影响,设计了大机动情况下滚动通道模型参考自适应变结构控制规律,利用变结构控制抗干扰能力强的特点将耦合作为干扰处理,同时采用模型参考自适应控制使得系统获得良好的动态特性。仿真结果表明,该控制规律可以有效解决大机动时滚动通道的耦合问题,从而避免古典控制方法导致的控制精度下降的缺陷。
Severe dynamic coupling is inevitable in rolling channel of torpedo during large maneuvering motion. In order to reduce the influence of coupling on roiling channel, this paper proposes a solution by combining model-reference adaptive control and variable structure control. The variable structure control law is used to handle the coupling which is regarded as interference, and the model-reference adaptive control law is used to improve dynamic performance of the system. Simulation results show that the control law can solve the coupling in rolling channel effectively under large maneuvering motion to avoid the deficient control accuracy of the traditional control methods.
