Abstract

The invention discloses a wide range speed regulation device for a torque motor. The device consists of a speed regulation command generator, a speed regulation controller, a power drive module, a speed regulation actuator and a speed sensor; the speed regulation controller consists of a comparator, an integrator, an integral coefficient multiplier, a subtracter, a PDF (Portable Document Format) coefficient multiplier, a PDF (Portable Document Format) follower, a feedback follower and an integral saturation limiter; the speed regulation actuator consists of the torque motor, a coupling and a mechanical load, wherein the comparator, the integrator, the integral coefficient multiplier, the subtracter, the power drive module, the torque motor, the coupling, the mechanical load, the speed sensor and the feedback follower are annularly connected in a clockwise direction; the comparator is also connected with the speed regulation command generator; the subtracter is also connected with the speed regulation sensor by the PDF coefficient multiplier and the PDF follower; and the integral saturation limiter is respectively connected with the output of the integral coefficient multiplier and the integrator. The wide range speed regulation device provided by the invention has the advantages of wide speed regulation range from zero to thousands of turns and excellent speed regulation performance.

Description

Technical field: [0001] The invention relates to a torque motor speed regulating device, in particular to a device whose speed can be stably and continuously adjusted within a wide range from zero to thousands of revolutions without a decelerating mechanism. Background technique: [0002] In the speed adjustment device, torque motor speed regulation is often encountered in many mechanical equipment and weaponry, such as the rotation of the mechanical arm, the rotary motion of the processing equipment, the transmission of the workpiece in the automatic production line, the search of the radar antenna, the aiming of the artillery Wait. In the torque motor speed control device, the adjusted variable is the movement speed of the mechanical load. In order to obtain the operating speed with lower mechanical load, a reduction device must be arranged between the torque motor and the mechanical load. In this way, not only the cost of the speed regulating device is increased, but al...
