Combined Control of Gearless Arc-Core Ship Radar Antenna Electric Drive With Fuzzy Logic Regulator

Abstract

The synthesis of a fuzzy proportional-integral-differential speed regulator of the arc stator electric drive of the rotation of the radar station antenna with combined control was carried out. The structural diagram of the fuzzy regulator was developed, the input and output linguistic variables are defined, the rule base was compiled, the dependence surfaces of the output control variable on the input coordinates are obtained. A simulation model of an electric drive in the Matlab system with a synthesized fuzzy logic regulator based on a two-phase model of an asynchronous arc-stator motor was built. Modeling of the nominal and the most difficult mode of operation of the electric drive was carried out, graphs of transient processes were obtained, which confirm its operability even under conditions of extreme loads.
