Design Optimization of Three-Loop Autopilot with Particle Swarm Optimization
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.
