So you can change your variables values at command window (or just at your script) and run Simulink model. One option I personally don't recommend is using a for-loop and calling the simulink model with a different value of roll and pitch for i = 1:numberOfTimestepsĪ second and more efficient approach is changing the constant blocks to other source blocks like ramp signals or sinusoid signalsįirst of all Simulink model use main Matlab workspace. There are multiple ways of achieving time dependent input variables: You can put a variable which is defined in the calling script. You can define the duration of your simulation in the block diagram editor. To get the outputs to your workspace you can use the simout block (make sure to put Save format to array).Ĭonnect outputs of your simulink model to the simout blocks. For the inputs you can use a constant block and when you double click the input block you can assign a value, which can be a workspace variable.

Is there a way to continuously feed inputs at every time step? This being controller module, I think I'm supposed to feed in different values based on output position and velocity.Ībout the first two points of your question:.

= sim('SimpleDroneDynamics.slx') Īnd got an error saying Number of left-hand side argument doesn't match block diagram. How do I get outputs with port numbers? I tried

How do I feed inputs using port numbers?.I got a warning saying: Input port 1 of 'SimpleDroneDynamics/.' is not connected. It takes in two inputs (roll cmd, pitch cmd) and outputs velocity x, velocity y, position x, and position y.įrom here, it seems like I can open the system by calling open_system('myModel.slx', 'loadable') īut how do I put inputs and get output values? slx Simulink model for drone dynamics system. I'm a super beginner in Simulink models and control systems.
