Fixed Wing Roll Angle Pid Current Control Algorithm
In view of the fixed-wing of the two-dimensional trajectory correction fuze,when the airfoil roll angle is updated during flight control.The existing methods,such as fuzzy control algorithm for slow control speed,dual closed-loop control algorithm,position speed dual loop PID algorithm,etc.,are complex in engineering im-plementation,therefore,a PID control algorithm based on current control roll angle was proposed.The algo-rithm input the difference between the target roll angle and the measured roll angle into PID control,the amount of change in angle was derived according to the torque balance relationship,then output control current,updated the roll angle,formed a closed loop to complete the control,which simplified the friction torque calculation method for easy engineering implementation.Simulation results showed that the algorithm met the control indi-cator requirements,and remained stable despite the introduction error,it had certain anti-interference ability and met the needs of the fixed-wing of the two-dimensional trajectory correction control requirements.
