| In order to study the satellite tracking of the target,this paper establishes the fractional order model of the satellite antenna servo system with the PMSM as the research object,and then studied the fuzzy fractional PID control algorithm.Researching on model and control algorithm of satellite antenna servo system,this paper mainly does the following work:First,the fractional order model of the satellite antenna servo system is established.According to the mathematical model of permanent magnet synchronous motor,the permanent magnet synchronous motor is divided into electromagnetic link and mechanical link.By preprocessing,the range of parameters to be identified is reduced.Then the parameters of the coral reef algorithm are improved to obtain the fractional model of PMSM.Combining the fractional-order model of PMSM with the speed loop controller and the current loop controller,the satellite antenna servo system model can be obtained.Secondly,the fuzzy PID controller is designed based on the fractional order model of the satellite antenna servo system.The fuzzy PID controller is used as the controller of the position loop of the satellite antenna servo system to carry out the simulation experiment.Finally,the fuzzy fractional PID controller is designed.The fractional PID controller is designed,and the fractional PID controller is used as the controller of the position loop to simulate the satellite antenna servo system.The fractional PID controller is combined with the fuzzy rules to design a fuzzy fractional PID controller.The fuzzy fractional PID controller is used to simulate the experiment. |
