ros_control with open loop system
Hello,
I want to ask one question and hopefully someone will help me with that. I am not so professional.
Is it possible to use ros_control pkg with open loop system. I mean I have a stepper motor without encoder, so I don't have the position of the motor, I calculating it just by summarize every time my command in pulses to the motor.
Because, as far as I understand the ros_control pkg require the close loop system to control it with PID.
Thank you in advance!
