Embodiment Construction

[0024] 1. The following is an explanation of the terms:

[0025] 1. PLC: Programmable Logic Controller (Programmable Logic Controller, PLC).

[0026] 2. Beckhoff: Beckhoff, Germany Beckhoff Automation Co., Ltd., mainly engaged in industrial automation production, PLC manufacturers.

[0027] 3. PID: In process control, the PID controller (also known as PID regulator) controlled by the proportional (P), integral (I) and differential (D) of the deviation is the most widely used automatic controller. It has the advantages of simple principle, easy implementation, wide applicability, independent control parameters, and relatively simple selection of parameters; and it can be proved theoretically that for the typical object of process control ─ ─ "first-order lag + pure lag" and The control object of "second-order lag + pure lag", PID controller is an optimal control. PID regulation is an effective method for continuous system dynamic quality correction, its parameter setting meth...

Abstract

The invention discloses and provides a force closed-loop control system based on a voice coil motor and a Beckhoff PLC core algorithm and a control method thereof, so that force output is more stable, force parameters can be adjusted in real time, force and position threshold protection is set, and safety of the system is enhanced. The system comprises a voice coil motor, a VCM driver, a power supply, a Beckhoff PLC controller, a force sensor, a signal amplifier, a pressing rod and a mounting bracket, wherein the power supply respectively supplies power to the VCM driver and the like; the Beckhoff PLC controller is connected with the feedback of the VCM driver and the feedback of the signal amplifier; the force sensor is fixedly installed below the voice coil motor and transmits a force sensor signal to the signal amplifier; the signal amplifier amplifies a signal of the force sensor and transmits the amplified signal to the Beckhoff PLC; the Beckhoff PLC sends a corresponding control signal to the VCM driver according to the received force sensor signal, and then the VCM driver controls the voice coil motor. The system is applied to the technical field of force closed-loop control systems.

Description

technical field [0001] The invention relates to a force closed-loop control system, in particular to a force closed-loop control system based on a voice coil motor and a Beckhoff PLC core algorithm and a control method thereof. Background technique [0002] Voice coil motor (Voice Coil Motor) is a special form of direct drive motor. It has the characteristics of simple structure, small size, high speed, high acceleration and fast response. Its working principle is that when the energized coil (conductor) is placed in the magnetic field, a force will be generated, and the magnitude of the force is proportional to the current applied to the coil. The movement form of the voice coil motor manufactured based on this principle can be a straight line or an arc, so Class motors are divided into cylindrical voice coil motors and swing voice coil motors. Cylindrical voice coil motor series are widely used in the market. This motor has a high acceleration rate and can generate a st...
