A position microelectric drive with two-channel control

摘要

Some questions related to developing a high-response speed two-zone microelectric d c. drive using two transistor converters are considered The drive can be used in different automatic control devices and in different instruments and apptratus operating in a positioning mode. A method for arranging a two-zone automatic control system is proposed, which takes into account the specifics of microelectric motors and uses a principle of independent control of magnetic flux. The laws to control the position of the actuator are formulated, which enable close-to-optimum dynamics of the automatic control system to be obtained in both the speed control zones. Practical recommendations on synthesizing the current, speed and position control loops within the above-mentioned automatic control system with two transistor converters are given.
