If you're looking for accurate speed and position control and minimal disturbance when you're working on designs that have multiple state transitions or dynamic changes, you're in luck. It's time to be concerned with your design's performance and reliability, instead of the speed and position loop calibration.
To build embedded position servo systems fast, Texas Instruments' InstaSPIN-MOTION includes support for an outer servo position loop that needs only a single tuning parameter for position plus velocity. The motor-control solution is powered by the SpinTAC software suite from LineStream Technologies, which provides robust control across dynamic speed, position, and load ranges in a fraction of the time.
The time-wasting issue is the hard-to-tune PID controllers. This suite provides a simple single tuning parameter for position and speed. InstaSPIN-MOTION allows you to test and tune your control quickly from soft to stiff response. The single gain typically works across the entire variable speed, position, and load range, reducing complexity and system tuning time in multi-variable PID-based systems. These systems often require a dozen or more velocity, position, and load tuned coefficient sets to handle all possible dynamic conditions, so the time savings is obvious.
The InstaSPIN-MOTION motor control software is embedded on TI's C2000 Piccolo F2806x MCUs. If you want to see it on display, and you'll be in Nuremberg next week at the SPS IPC Drives conference (Nov. 26-28), you'll be in luck.
