I am currently trying to model an actuator that turns a shaft every 90 degrees. The ODE for this apparatus is very simple but there are very few and unique constraints for this.
The constraints are the position ranges from 0 to 90 degrees and inital conditions of all zeroes except for acceleration. Since there is no distinct time interval for this model, I am not sure how to incorporate this into the traditional ode23 or ode45 commands.
Is there a way to do this or is there another ODE command I can use that is setup for constraints such as mine?
