DMC2 50412P-CAN 工作原理

伺服驅(qū)動(dòng)器的工作原理主要包括信號(hào)處理、PID調(diào)節(jié)、電流控制和驅(qū)動(dòng)輸出等幾個(gè)部分：

信號(hào)處理：伺服驅(qū)動(dòng)器首先對(duì)接收到的上位機(jī)指令進(jìn)行信號(hào)處理，包括解碼、濾波、采樣等操作，將上位機(jī)指令轉(zhuǎn)換為適合伺服電機(jī)控制的信號(hào)。

PID調(diào)節(jié)：根據(jù)信號(hào)處理后的信號(hào)，通過PID（比例-積分-微分）調(diào)節(jié)器對(duì)伺服電機(jī)的控制參數(shù)進(jìn)行調(diào)整。PID調(diào)節(jié)器根據(jù)誤差信號(hào)的大小和變化趨勢(shì)，計(jì)算出相應(yīng)的控制量，從而實(shí)現(xiàn)對(duì)伺服電機(jī)的精確控制。

電流控制：根據(jù)PID調(diào)節(jié)器的輸出，通過電流控制器對(duì)伺服電機(jī)的電流進(jìn)行控制。電流控制器調(diào)整伺服電機(jī)的電流大小和方向，確保電機(jī)按照預(yù)定方式運(yùn)行。

驅(qū)動(dòng)輸出：將電流控制器的輸出信號(hào)轉(zhuǎn)換為驅(qū)動(dòng)信號(hào)，通過驅(qū)動(dòng)電路驅(qū)動(dòng)伺服電機(jī)工作。驅(qū)動(dòng)電路包括功率放大器、脈沖生成器等部件，可以實(shí)現(xiàn)對(duì)伺服電機(jī)的高效驅(qū)動(dòng)。

有足夠的傳動(dòng)剛性和高的速度穩(wěn)定性：確保電機(jī)在高速運(yùn)轉(zhuǎn)時(shí)仍能保持穩(wěn)定的性能。

Working principle of DMC2 50412P-CAN

The working principle of servo driver mainly includes signal processing, PID regulation, current control and drive output:

Signal processing: The servo driver first conducts signal processing on the received instructions of the upper computer, including decoding, filtering, sampling and other operations, and converts the instructions of the upper computer into signals suitable for the control of the servo motor.

PID adjustment: According to the signal after signal processing, the control parameters of the servo motor are adjusted through the PID (proportional-integral-differential) regulator. The PID controller calculates the corresponding control amount according to the size and change trend of the error signal, so as to realize the precise control of the servo motor.

Current control: According to the output of the PID regulator, the current of the servo motor is controlled by the current controller. The current controller adjusts the current size and direction of the servo motor to ensure that the motor operates in a predetermined manner.

Drive output: The output signal of the current controller is converted into a drive signal, and the servo motor is driven by the drive circuit. The drive circuit includes power amplifier, pulse generator and other components, which can realize the efficient drive of servo motor.

DMC2 50412P-CAN Basic requirements

Servo drivers need to meet the following basic requirements in the design and application process:

Wide speed range: from the lowest speed to the highest speed motor can run smoothly, torque fluctuation is small.

High positioning accuracy: It can realize high-precision position control of servo motor.

Sufficient drive rigidity and high speed stability: ensure that the motor can maintain stable performance at high speed.

Fast response: It can quickly respond to the command signal of the host computer to achieve accurate control without overshoot.
