Hello, I have a question in regards to simulink. I am currently working on an LQR controller for a quadrotor. However before I can get into the control aspect of it I would like to be able to input my model into simulink via 3 second order differential equations. Is this possible? I have initial conditions. The differential equations model a quadrotor and initial condition are all zero. aka hovering.
equations can be found on page 2 on the left hand side if interested:
Another question: Can Matlab linearize my system of 3 nonlinear equations around some trim condition such as hovering?
Thank you

Hi, may I know did you already success in the linearization part? I got some problem, I used the nonlinear model of Quad rotor, but since I want to used LQR as the controller, I need the linearization part. But what should I do to get the linearization equation? Tq :)
