Abstract

The invention relates to the technical field of three-channel flow regulation, especially to a three-channel flow regulation control method and a three-channel flow control adjusting apparatus, and a servo control drive system. The flow regulation control method comprises: S1, whether a received control instruction is a self-checking instruction is determined; if so, a step S2 is executed; and if not a step S3 is executed; S2, three actuators are electrified and are kept to be at original locations; whether the three actuators are synchronized is determined based on feedback location information; if so, the original location is kept; and if not, automatic centering is carried out, and then a step S6 is executed; S3, whether a control instruction is a motion instruction is determined; if so, a step S7 is executed; S4, location closed-loop controlling is carried out on the three actuators and then a step S5 is executed; S5, whether the three actuators are synchronized is determined; if so, the step S6 is executed; and if not the step S7 is executed; S6, the three actuators are controlled to make synchronization motions; and S7, a servo actuator does not make motion.

Description

technical field [0001] The invention relates to the technical field of three-channel flow adjustment, in particular to a three-channel flow adjustment control method, a control adjustment device and a servo control drive system. Background technique [0002] As an important part of the electro-hydraulic servo mechanism, the flow adjustment servo mechanism control driver directly drives the control valve and drives the servo actuator to realize servo control. [0003] The flow adjustment of the engine nozzle requires the three-channel servo mechanism to have high dynamic characteristics, and the three-channel servo mechanism needs to maintain the synchronization of the action during the movement process. And its volume is smaller than the servo mechanism designed in the past, and it must withstand more severe high-temperature environmental conditions. Most of the existing electro-hydraulic servo mechanisms have a symmetrical structure, and there is no precision requirement fo...
