针对导弹自动驾驶仪控制参数设计问题及耦合对控制系统设计的影响,提出了一种基于PSO算法的三通道耦合状态空间控制参数设计方法。建立了自动驾驶仪三通道全状态耦合线性化模型,通过对线性化模型的建立、控制系统性能指标的选取、PSO算法的参数设置及适应度函数的编写,实现了基于PSO算法对自动驾驶仪控制参数的自动设计。仿真结果表明,该方法设计的控制参数优于三通道解耦独立设计的控制参数,设计结果具有良好的动态品质和鲁棒性,并具有较快的收敛速度和良好的全局搜索能力,是一种有效的控制参数自动设计方法。
Aiming at the design problem of missile autopilot control parameters and the influence of coupling on control system design, a three-channel coupling state space control parameter design method based on PSO algorithm is proposed. The three-channel full-state coupled linearization model of autopilot is established. By setting up the linearization model, selecting the control system performance parameters, setting the parameters of the PSO algorithm and writing the fitness function, the autopilot Automatic control parameter design. The simulation results show that the control parameters of the proposed method are better than those of the three-channel decoupled independent design. The design results have good dynamic quality and robustness, fast convergence speed and good global search ability Effective control parameter automatic design method.
