摘　　要：针对导弹拦截机动目标及导弹执行机构存在物理受限的问题,研究了三维非线性抗饱和制导律的设计问题,基于径向基函数神经网络法以及自适应法设计了抗干扰以及抗饱和的终端滑模制导律,该制导律是有界的并且能够保证系统状态一致最终有界,与传统抗饱和制导律相比具有收敛速度快和精度高的优势。进行了理论证明。给出数学仿真实验结果,验证了所设计制导律的有效性以及优越性。The problem of designing a three-dimensional nonlinear guidance law accounting for saturation nonlinearity is concentrated to attack maneuvering targets. To solve the physical constraints of missile actuators, an anti-disturbance and anti-saturation terminal sliding mode guidance law is provided based on radial basis functions neural networks and adaptive method. The guidance law is bounded and ensures that the system state is uniformly ultimately bounded. Compared with the traditional anti-saturation guidance law, it has the advantages of fast convergence speed and high precision. Numerical simulations are introduced to demonstrate the effectiveness and superiority of the designed composite guidance law in theory.
