CCS/LAUNCHXL-F28069M: Spintac speed and position controller

Part Number: LAUNCHXL-F28069M
Other Parts Discussed in Thread: MOTORWARE

Tool/software: Code Composer Studio

hello,

I was able to do motorware lab 12b speed controller  and lab 13b position controller. I see that TI is using SPINTAC technology (using bandwidth parameters) instead of PI controllers. my question is what calculations are taking place inside the spintac speed control block or spintac position control block. is the position control loop cascaded around the speed control loop in lab 13b?

    You must run lab02b to identify the motor parameters and run lab 12a to identify the motor inertia and friction first. And then set these parameters in user.h for the subsequent lab12b or lab13b.

    Please ensure that the physical connections of both motor and encoder are done correctly, and encoder lines number is set to USER_MOTOR_ENCODER_LINES in user.h as well.
