Introduction
Radarsystemsareusedfortrackinganddetectingtargetsinvariousapplications,includingaviation,military,naval,andweatherforecasting.Thesesystemsconsistofseveralcomponentssuchastheradartransmitter,antenna,receiver,andsignalprocessor.Theradarantennaisacriticalcomponentofaradarsystemandrequiresaccuratepositioningandtrackingofthetarget.Theantennalockingsystemisusedtoprovideprecisepositioningandtrackingoftheantennawithrespecttothetarget.Thelockingsystemusesservomotorsandcontrolsystemstoachieveaccuratepositioningandtracking.
DesignoftheRadarAntennaLockingSystem
Thedesignoftheradarantennalockingsysteminvolvestheselectionoftheservomotor,themechanicalsystem,andthecontrolsystem.Theservomotorisselectedbasedonthetorqueandspeedrequirementsofthesystem.Themechanicalsystemincludestheantennastructure,thepositionencoder,andthegearsystem.Thepositionencoderisusedtomeasurethepositionoftheantenna,whichisusedforfeedbacktothecontrolsystem.Thegearsystemisusedtoincreasethetorqueoftheservomotor.
Thecontrolsystemisdesignedusingaproportional-integral-derivative(PID)controller.ThePIDcontrollermeasurestheerrorbetweenthedesiredpositionandtheactualpositionoftheantennaandprovidesacorrectivesignaltotheservomotor.ThePIDcontrollerisdesignedusingtheZiegler-NicholsmethodfortuningthePIDcontrollerparameters.
