Description

technical field [0001] The invention relates to the technical field of servo drive control, in particular to an AC servo electric cylinder drive control circuit for an infrared warning and stabilization platform. Background technique [0002] The servo electric cylinder is an infrared warning and stable platform movement actuator. The electric cylinder integrates the built-in AC permanent magnet synchronous motor and the roller screw transmission mechanism. The rotary motion of the servo motor rotor is directly converted into the push rod through the roller screw mechanism. linear motion. The servo control of the electric cylinder can be attributed to the servo control of the AC permanent magnet synchronous motor. [0003] At present, with the emergence of high-performance digital processors, domestic and foreign companies have developed a variety of all-digital AC servo drives based on DSP, but the AC servo electric cylinder drive control circuit for infrared warning and s...
