represent servo angle motion

[truongpm]

Without going into detail with the PWM signals/actual servo mechanics, how can I command a body to rotate to some angle with some constant angular velocity? My control system's actuator is a small, constant-force rocket thruster attached to a servo, so the servo needs to move to certain angles to produce the desired moment on the system.

I am using SimMechanics, and if I use the joint actuator (motion) to command a desired angle and specify any angular velocity, the servo still moves instantaneously. I need to be able to account for the torque produced from the time it takes to move to the actual angle.



Thanks.

Sort of. I am starting graduate school soon and would like to be more skilled with Simulink/SimMechanics for aerospace applications. I figured I start with an inverted pendulum controlled by vernier thrusters and work my way up to simulating a rocket controlled by thrust-vectoring. The same problem I have is that I cannot account for the response of the actuator.
