Less code (60% reduction), less oscillation, worse accuracy.

This is a little more difficult than feedback where the signal is proportional to the distance. In this case we are targeting for a local maximum. The approach used here also addresses the case where the object moves (although you would need to delete "app.gui.playmode = sim.running" in the sensor target to try it) which is a little tricky because the sensor can't determine which way the object is moving.

Nice "tight" control.:tup: Did you use PID algorithm for the position control?

No, just P. I'm not sure how to do "I" in this case. If I did, then maybe I could reduce the error.

I'm sure that you already know that "I' would reduce the error between the position setpoint and the measured position during steady-state conditions. It integrates the error over a preset time period, and continuously nudges the load being moved until the error is zero. "I" is only needed in applications where extreme position accuracy is required during steady-state conditions (no accel or decel). The bottom line is, if you don't need "I" then you are better off without it.
