運(yùn)動(dòng)控制模塊是機(jī)器人控制器最核心的功能模塊,DS215DMCBG1AZZ03A根據(jù)接收到的運(yùn)動(dòng)命令,進(jìn)行運(yùn)動(dòng)學(xué)解算或者軌跡規(guī)劃運(yùn)算,得到在每個(gè)伺服控制周期內(nèi)各個(gè)關(guān)節(jié)的角度值,并發(fā)送到伺服驅(qū)動(dòng)系統(tǒng),使機(jī)器人的末端可以在三維空間中完成指定的路徑或者姿態(tài)變化。其工作原理可以進(jìn)一步細(xì)分為以下步驟:

接收運(yùn)動(dòng)命令:運(yùn)動(dòng)控制模塊從上位機(jī)接收運(yùn)動(dòng)命令,這些命令通常包括需要到達(dá)的目標(biāo)位置、速度和加速度等參數(shù)。

運(yùn)動(dòng)學(xué)解算:對(duì)于關(guān)節(jié)型機(jī)器人,需要將目標(biāo)位置和姿態(tài)轉(zhuǎn)換為每個(gè)關(guān)節(jié)的位置和角度。這一步通常涉及運(yùn)動(dòng)學(xué)正逆解算,即根據(jù)目標(biāo)位置和姿態(tài)求解每個(gè)關(guān)節(jié)的角度,或者根據(jù)關(guān)節(jié)角度計(jì)算末端執(zhí)行器的位置和姿態(tài)。

軌跡規(guī)劃:為了平滑地從一個(gè)姿態(tài)移動(dòng)到另一個(gè)姿態(tài),需要規(guī)劃出一條平滑的軌跡。這一步通常涉及插補(bǔ)算法,如直線插補(bǔ)和圓弧插補(bǔ),以生成連續(xù)平滑的軌跡。

控制算法:采用適當(dāng)?shù)目刂扑惴▉?lái)確保機(jī)器人按照規(guī)劃的軌跡進(jìn)行運(yùn)動(dòng)。常用的控制算法包括PID控制、模糊控制等。這些算法可以根據(jù)機(jī)器人的實(shí)時(shí)位置和速度與目標(biāo)值之間的誤差來(lái)計(jì)算出適當(dāng)?shù)目刂菩盘?hào)。

輸出控制信號(hào):將計(jì)算出的控制信號(hào)發(fā)送給伺服驅(qū)動(dòng)系統(tǒng),以驅(qū)動(dòng)每個(gè)關(guān)節(jié)電機(jī)轉(zhuǎn)動(dòng)。這些信號(hào)通常包括電機(jī)的目標(biāo)轉(zhuǎn)速和目標(biāo)轉(zhuǎn)矩。

實(shí)時(shí)反饋:通過傳感器實(shí)時(shí)監(jiān)測(cè)機(jī)器人的位置、速度等狀態(tài)參數(shù),并將這些參數(shù)反饋給運(yùn)動(dòng)控制模塊。根據(jù)反饋信息,控制模塊可以調(diào)整控制信號(hào)以確保機(jī)器人精確地跟蹤目標(biāo)軌跡。

通過以上步驟,DS215DMCBG1AZZ03A運(yùn)動(dòng)控制模塊實(shí)現(xiàn)了對(duì)機(jī)器人運(yùn)動(dòng)的精確控制,使得機(jī)器人能夠按照預(yù)設(shè)的軌跡和姿態(tài)進(jìn)行運(yùn)動(dòng)。

The motion control module is the core functional module of the robot controller. DS215DMCBG1AZZ03A performs kinematics calculation or trajectory planning operations according to the received motion commands, obtains the Angle values of each joint in each servo control cycle, and sends them to the servo drive system. The end of the robot can complete the specified path or attitude change in the three-dimensional space. How it works can be further broken down into the following steps:

Receive motion commands: The motion control module receives motion commands from the host computer, which usually include parameters such as the target position, speed and acceleration that need to be reached.

Kinematic solution: For a jointed robot, the target position and attitude need to be converted into the position and Angle of each joint. This step usually involves a forward and inverse kinematics solution, that is, solving the Angle of each joint based on the target position and attitude, or calculating the position and attitude of the end effector based on the joint Angle.

Trajectory planning: In order to move smoothly from one attitude to another, a smooth trajectory needs to be planned. This step usually involves interpolation algorithms, such as straight line interpolation and arc interpolation, to generate continuously smooth trajectories.

Control algorithm: The appropriate control algorithm is used to ensure that the robot moves according to the planned trajectory. Commonly used control algorithms include PID control, fuzzy control and so on. These algorithms can calculate the appropriate control signal based on the error between the real-time position and speed of the robot and the target value.

Output control signal: The calculated control signal is sent to the servo drive system to drive each joint motor to rotate. These signals usually include the target speed and target torque of the motor.

Real-time feedback: the position, speed and other state parameters of the robot are monitored in real time by sensors, and these parameters are fed back to the motion control module. Based on the feedback, the control module can adjust the control signal to ensure that the robot accurately tracks the target trajectory.

Through the above steps, the DS215DMCBG1AZZ03A motion control module realizes the precise control of the robot motion, so that the robot can move according to the preset trajectory and attitude.
