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...
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...
Hey,
I am trying to understand the effects of motor backlash and how to possibly model it in Matlab/simulink. The system I am trying to model is a servo turning an active rocket thruster (think vernier thruster for attitude control). What would be the best tool for this issue in simulink?
Hi,
I am trying to practice with simulink and fuzzy logic on the inverted pendulum system. I am following this website's PID example, but would like to substitute PID with fuzzy logic:

My main question at this point is...
Thanks for the responses guys!
FeX32, if I analyzed about the joint, would the DE simply be thetaddot = 1/(Icg + mL^2) * mgLsin(theta)? And everything else would remain the same in the link I showed?
Hmm.. I guess they are treating the rod and cart separately and doing the equations of motion based on that, so you are right about translation and rotation about the rod's cg. As for the coupling, that is handled by defining what those interaction forces (N and P) are?
Hi,
I have been trying to understand the dynamics behind an inverted pendulum from this webpage:
http://www.library.cmu.edu/ctms/ctms/simulink/examples/pend/pendsim.htm
I don't get what the moment of inertia (I) of the rod is. I was thinking it should be about the end of the rod: m*(2L)^2...
