Hello. I've posted two other posts about my project designing and controlling a Ball and Beam system, with links attached below. As I'm doing it for an engineering project, I'm supposed to model the system mathematically, calculate the PID parameters, etc. A step of modelling the system is to find the input voltage of the servo. I've come across many research papers using this equation to find it:
This is a general motor equation, with I being the armature current, Ra being the armature resistance, Km as the motor torque constant, etc. My question is: Is there a way, if they exist, to find thsese values for a servo motor? The other question is, does a servo motor even have varying voltage input, or is its input a constant one, i.e. the rated one in its datasheet?
It is the same project, NOT the same topic. It is evidenced by your reply in each one that they do not talk about the same thing. I had had this discussion already with a moderator and was advised that I should leave links to other related posts, shall I decided to ask separate questions about the same project, which is what I did. Yet, I have already received my reply, so I wouldn't mind it being closed. Thank you for your assistance.
I understand Your approach. However criss crossing through 2 other topics make it a lot more heavy and time consuming. Helpers will turn their back to this topic.
Post facts, links to the motor etc. here in this topic. Reading data sheets ought to be within Your capacity at Your position in the company...
The PID constants depend on a lot more then the motor. The mechanism attached to the motor is highly important to know. What play, what hysteresis are there? Torque needed versus motor torque...
The issue is that I'm using a servo motor, not a DC one. Therefore, its datasheet and operation is completely different. That's why I was wondering if I was able to extract the variables in the equation from a servo motor, because I never saw the equation parameters mentioned in their datasheets.
