摘要: 为了解决大跨速鱼雷速度的大范围变化对精确控制的影响, 设计了线性自抗扰控制器。首先, 为了便于设计, 对鱼雷横滚控制数学模型进行了重新推导; 然后将自抗扰控制应用到鱼雷横滚控制中, 实现了对总扰动的估计和实时补偿。仿真结果表明, 该控制器可适应鱼雷28~70 kn速度的大范围变化, 不仅能很好地估计并补偿总扰动, 而且对鱼雷参数的不确定性具有较强的鲁棒性, 可满足大跨速鱼雷横滚通道控制要求, 性能指标明显优于比例-积分-微分控制。Abstract: To overcome the difficulties of a large range of variations in the velocity of a wide-speed torpedo on precise control, a linear active disturbance rejection control(ADRC) method is designed. First, the mathematical model of rolling control is derived for a wide-speed torpedo for a convenient design. Next, the proposed ADRC is used for the rolling control of the torpedo to estimate and compensate for the total disturbances in real time. Simulation results show that the designed controller can adapt to a wide speed range of 28~70 kn. Furthermore, it can accurately estimate and compensate for the total disturbances and account for the uncertainty of the torpedo parameters. Thus, the proposed controller fulfills the requirements of a controller of the roll channel for a wide-speed-scope torpedo and its performance is superior to that of a proportional-integral-differential control
