Write a control motor action in MFC procedures, according to certain rules first motor action works (forward - stop - forward -... - stop), there are two ways:
A: to create A thread to control the motor operation all the code written in this thread (infinite loop), and then through A message awakened thread;
B: the motor running every movement as a message (forward, stop message), and then send you the message loop in the thread for the motor running,
Consult everybody a great god, and that the two methods is better? Or have any better ideas, thanked the first

Look at your request, if the motor drive had been reached, the PC is just communication, then see your response frequency, under the condition of the switching frequency is not high, the problem is not big; The demand is higher, if the frequency is not appropriate; If directly by computer control motor speed, the above methods are not,

CodePudding user response:

A, B is nonsense, B itself run don't need A thread to run?

CodePudding user response:

PC is usually to control motor speed,
Motor itself should have a speed loop, current loop,
Upper machine position loop or a possible,

Miss zhao, I'm serious look at this article

A ok, control motor operation will not get stuck in A child line the UI

Thank you for your answer, motor drive is normal, the PC just to motor control commands via a serial port sent to the motor, don't need a high response frequency, so long as can realize the process

Thank you for your answer, the younger brother novice, still hope glad, thanks again

Thank you for your answer, the control of motor speed command can already by the upper machine through a serial port communication to motor, and can run normally, now want to achieve such a cycle test process,

Can only be A
B no real-time cannot reach satisfactory, or wrong,
If use servo control card control, not to mention the can only create a thread to manage him, let he's turn, reverse, stop and so on,
The servo load is not big case can still achieve satisfied effect, if big get through lots of experiments to let him run stability,
