	Unlike traditional PID loops where a target is set and the controller approaches (often aggressively), Phidget velocity controllers will intelligently plot a series of target velocities between the current and desired velocity. This is shown as the ''Expected Velocity'' in the graph above. The controller will follow the user-specified acceleration plot these points. A PID loop is then employed to precisely follow this trajectory, ensuring smooth and controlled motion.

			==Motion Profiling==
			Trapezoidal motion profiling combined with a proportional-integral-derivative (PID) controller is used in order to accurately track velocity. This allows for advanced control and improved repeatability of your system.
