摘要
提出了一种伪攻角三回路自动驾驶仪的设计方法,从控制系统的开环性能指标出发,在舵控处依次断开增稳回路和过载回路,建立开环参数与伪攻角三回路自动驾驶仪参数的关系式,并以开环性能参数为自变量,闭环性能参数为优化目标,设计粒子群算法结构与边界条件,实现伪攻角三回路自动驾驶仪的快速调参.仿真结果表明,本文提出的设计方法,可使伪攻角三回路自动驾驶仪获得良好的开环性能和闭环性能,具有一定的工程应用价值.
Abstract
A designed method is proposed in this paper for the parameter adjustment of three-loop autopilot with pseudo-angle.Ulteriorly,regarding the open-loop performances indexes of the control system,the sta-bilizing and the overload loops are successively disconnected at the rudder control,and the relationship is es-tablished between open-loop parameters and the three-loop autopilot parameters with pseudo-angle.Then,by taking the open-loop performance parameters as independent variable and the closed-loop performance pa-rameter as optimization goal,particle swarm optimization algorithm structure and boundary conditions are designed,and the quickly parameters adjustment of three-loop autopilot with pseudo-angle is realized.The simulation results show that good open and closed loop performance of three-loop autopilot can be achieved through the designed method based on particle swarm optimization.
