CE30089 伺服控制模塊會(huì)以電壓和加工力的輸出值與設(shè)定值進(jìn)行對(duì)比

伺服控制模塊是控制系統(tǒng)中非常重要的組成部分，CE30089主要負(fù)責(zé)工具在線制備的自動(dòng)加工和微細(xì)超聲波的自動(dòng)加工過程的控制。為了滿足加工精度要求，伺服控制模塊通常采用閉環(huán)控制策略。

在工具制備和超聲加工過程中，伺服控制模塊會(huì)以電壓和加工力的輸出值與設(shè)定值進(jìn)行對(duì)比，將偏差作為反饋信號(hào)來控制微細(xì)工具的進(jìn)給和后退，使加工間隙始終維持在一定的范圍內(nèi)。這種控制策略確保了加工的精確性和穩(wěn)定性。

伺服控制模塊的具體控制策略是，在開始實(shí)驗(yàn)前設(shè)置好加工力或者電壓的上下限值及前進(jìn)速度值和后退速度值。當(dāng)實(shí)時(shí)反饋的加工力信號(hào)或者電壓信號(hào)值大于上限值時(shí)，被控制的進(jìn)給軸以設(shè)定好的后退速度后退；當(dāng)實(shí)時(shí)反饋的信號(hào)小于下限值時(shí)，進(jìn)給軸以前進(jìn)速度前進(jìn)；當(dāng)信號(hào)介于上下限之間時(shí)，進(jìn)給軸保持靜止并進(jìn)行加工。

此外，伺服控制模塊CE30089的設(shè)計(jì)也需要考慮系統(tǒng)的冗余度。最簡單的伺服控制系統(tǒng)是單個(gè)控制芯片負(fù)責(zé)控制對(duì)應(yīng)的電液伺服閥，但由于控制回路不具有備份余度，一旦控制輸出或者信號(hào)采集發(fā)生故障，整個(gè)伺服控制系統(tǒng)便無法正常工作。為了增強(qiáng)系統(tǒng)的魯棒性，伺服控制系統(tǒng)通常設(shè)計(jì)成多余度架構(gòu)，當(dāng)單個(gè)余度出現(xiàn)故障時(shí)，其他余度的控制回路仍然能夠正常工作。

總之，伺服控制模塊是確保加工精度和系統(tǒng)穩(wěn)定性的關(guān)鍵部分，其設(shè)計(jì)和實(shí)現(xiàn)需要綜合考慮多種因素，以滿足不同應(yīng)用場景的需求。

Servo control module is a very important part of the control system, CE30089 is mainly responsible for the automatic processing of online tool preparation and micro-ultrasonic automatic processing control. In order to meet the requirements of machining accuracy, servo control module usually adopts closed-loop control strategy.

In the process of tool preparation and ultrasonic machining, the servo control module will compare the output value of voltage and machining force with the set value, and use the deviation as a feedback signal to control the feed and retreat of the micro-tool, so that the machining gap is always maintained within a certain range. This control strategy ensures the accuracy and stability of the machining.

The specific control strategy of the servo control module is to set the upper and lower limits of the machining force or voltage and the forward and backward speed values before starting the experiment. When the value of the real-time feedback machining force signal or voltage signal is greater than the upper limit value, the controlled feed shaft retreats at the set backward speed; When the real-time feedback signal is less than the lower limit value, the feed shaft advances forward speed; When the signal is between the upper and lower limits, the feed shaft remains stationary and is processed.

In addition, the design of servo control module CE30089 also needs to consider the redundancy of the system. The simplest servo control system is a single control chip responsible for controlling the corresponding electro-hydraulic servo valve, but because the control loop does not have backup redundancy, once the control output or signal acquisition failure, the whole servo control system will not work normally. In order to enhance the robustness of the system, the servo control system is usually designed with redundancy architecture, when a single redundancy fails, the other redundancy control loops can still work normally.

In short, the servo control module is a key part to ensure machining accuracy and system stability, and its design and implementation need to consider a variety of factors to meet the needs of different application scenarios.
