Embodiment

[0046] Such as Figure 4 shown.

[0047] 1. The initialization state is slow return to zero. After returning to the zero position, it receives a control command, jumps out of the automatic zero return operation, and enters the normal closed-loop state.

[0048] Such as figure 2 and image 3 As shown, when the control command 101 is not sent to the servo control driver 2, and the four electromechanical actuators are respectively at +12mm, +8mm, -5mm, -15mm positions (none of which are at the 0mm position), the servo control driver has completed initialization At the same time, the power supply is powered on, the servo system works, and the four-way electromechanical actuator command is assigned as 0mm. At this time, the control instruction type determiner 202 determines that the current state is a slow closed-loop control state. The control command type determiner 202 controls the position loop output limiter switch 203 to output the operation result of the control positio...

Abstract

A multi-channel regulating system and method for AC permanent magnet synchronous motor actuators belong to the technical field of space servo motor control. The status of a control instruction received by a servo control driver is judged by a control instruction type judging device in the servo control driver in each cycle, so as to achieve an effect of reliably exiting from the initial amplitudelimit, solve the problem that the instructions between a servo control driver and a host computer are complex and achieve the purpose of high priority of a fast amplitude limiter. By changing an output amplitude limiter in the servo control driver, slow return to zero in the initial state is achieved, and the rated load can be promoted.

Description

technical field [0001] The invention relates to a multi-channel adjustment system and method for an AC permanent magnet synchronous motor actuator, in particular to a variable control structure control system and method for controlling an electromechanical actuator based on a permanent magnet synchronous motor, and belongs to the technical field of aerospace servo motor control . Background technique [0002] The servo control driver is a servo control device, and the control actuator realizes the position action according to the corresponding position command sent by the host computer. The actuator is divided into permanent magnet synchronous motor, ball screw assembly and displacement sensor. The controlled object of the servo control driver is an electromechanical actuator using a permanent magnet synchronous motor; one servo control driver can control four electromechanical actuators. When the initial position of the electromechanical actuator is not at the default pos...
