Abstract

The invention discloses a torque motor wide range speed regulation numerical control device and a control method thereof. The control device comprises a numerical control computer, a digital / analog conversion module, a power driving module, a torque motor, a coupler, a mechanical load, a photoelectric encoder and a high-speed counting module, which are sequentially connected in a clockwise direction to form a ring. The control method comprises the steps as follows: initializing an integrator, reading a speed numerical instruction signal and a speed numerical feedback signal, and obtaining an error signal by comparing the speed numerical instruction signal and the speed numerical feedback signal; obtaining an integral product through that errors are accumulated, integrated and multiplied by integral coefficient; obtaining a PDF product through that the speed numerical feedback signal is multiplied by PDF coefficient; and obtaining a numerical quantity difference value through the PDF product is subtracted from the integral product, obtaining an analog quantity control signal by executing digital / analog conversion of the difference value, and controlling a speed regulation executing mechanism via the power driving module, thereby ensuring the favorable performance of speed regulation in a wide range.

Description

Technical field: [0001] The invention relates to a torque motor digital speed regulating device, in particular to a torque motor wide-range digital control device and a control method. Background technique: [0002] Torque motor speed regulation is often encountered in many mechanical equipment and weaponry. In order to obtain a lower operating speed with 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 also the volume and weight of the speed regulating device are increased. Even with the configuration of the deceleration device, the performance of the torque motor speed control device is still unstable when running at low speed, especially when running at extremely low speed, due to load changes or external interference, it often happens that it cannot run continuously and smoothly, that is The so-called crawling phenomenon. [0003] In ord...
