Slow servo and pixhawk

Posted by PacificBots on July 13, 2015 at 11:29am

Working on a seond project. this one uses a linear actuator to steer a rudder on a 5 meter boat.

The travel time for the actuator is .5"\sec.

The stroke is 1.96"

My concern here is that with the slow travel time the servo might not be fast enough to keep up with the pixhawk.

Is there a way to delay servo commands from the pixhawk? 

Or am I just tilting at windmills?

Thanks as always

    I have been experimenting with STEER2SRV_TCONST but getting such a large boat out onto the water for an empirical test can be daunting. 

    I think this would be a perfect job for simulation software.

    I would think the parameters could be adjusted to deal with this.  My 4 foot catamaran does not turn very fast and I have been able to tune it to run a fairly true course.
