Abstract

The invention discloses a method for accurately controlling the starting process of a direct-current torque motor, and aims at the problem of large starting torque of the direct-current torque motor. The method comprises firstly, the starting position angle of the motor is determined according to various performance indexes of a system, then whether the motor is started or not is judged, and if not, a master command is controlled to adopt proportional and integral output; meanwhile, a selection method of proportion and integral parameters is given; amplitude limiting processing is carried out on the control master command; and finally, after the motor is started, the motor is controlled to rotate at a stable speed through fixed master command output. The method can be used to effectively ensure that the direct-current torque motor is normally started within the specified time, and the system reliability is improved. The method has the advantages of being simple in implementation method, accurate in calculation data, effective in engineering practice and the like.

Description

technical field

[0001] The invention relates to the technical field of servo control system motor control, in particular to a precise control method for the starting process of a DC torque motor. Background technique

[0002] At present, in domestic products such as seeker servo platforms and photoelectric trackers, DC torque motors are mostly used as actuators. DC torque motors are ideal for direct drive servo applications, while minimizing size, weight, power and response time. while maximizing speed and position accuracy. The DC torque motor provides a servo drive that can be directly connected to the driven load.

[0003] DC torque motor can provide ultra-low speed and high torque for ideal positioning and speed control system, or high response speed and optimal torque; it has the following characteristics: frameless installation mode and optional large torque range; high Torque to inertia ratio for fast start / stop and high acceleration; high torque to power ratio for ...
